1-3 Safety information
1-3-1 Safety information
(1) Laser safety
This printer is certified as a Class 1 laser product under the U.S. Department of Health and Human
Services (DHHS) Radiation Performance Standard according to Radiation Control for Health and
Safety Act of 1968. This means that the printer does not produce hazardous laser radiation. Since
radiation emitted inside the printer is completely confined within protective housings and external
covers, the laser beam cannot escape from the printer during any phase of user operation.
(2) Laser notice
This printer is certified in the U.S. to conform to the requirements of DHHS 21 CFR Subchapter for
Class I (1) laser products, and elsewhere is certified as a Class I laser product conforming to the
requirements of IEC 825.
(3) Laser caution label on the scanner unit
The laser scanner unit inside the printer has the following label affixed on its top. Observe the laser
radiation warning and figures when handling the laser scanner unit.
1-12FS-1800/1800N | FS-3800/3800N

(4) CDRH regulations (U.S.A.)
The Center of Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration
implemented regulations for laser products on August 2, 1976. These regulations apply to laser
products manufactured after August 1, 1976. Compliance is mandatory for products marketed in
the United States. A label indicating compliance with the CDRH regulations must be attached to
laser products marketed in the United States.
(5) Ozone concentration
The printers generate ozone gas (O3) which may concentrate in the place of installation and cause
an unpleasant smell. To minimize concentration of ozone gas to less than 0.1 ppm, we recommend
you not to install the printer in a confined area where ventilation is blocked.
(6) FCC statement (U.S.A.)
a) For the FS-1800 and FS-3800 models
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interferences to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the manufacturer for compliance could void
the user’s authority to operate the equipment. Shielded circular cable should be used for interfacing

b) For the FS-1800N and FS-3800N models
This equipment has been tested and found to comply with the limits for Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his own expense.

• Near an AC wall outlet, preferably one that can be used for the printer alone. The outlet should
have a ground slot, or an adapter should be used. If you use an extension cord, the total length of
the power cord plus extension cord should be 17 feet or 5 meters or less.
• Well ventilated, not too hot or cold, and not too damp or dry (See section Environmental
requirements on page 1-5). If you install the printer where the temperature or humidity is outside
the requirements in section Environmental requirements in chapter 1, the best print quality may
not be expected and there will be an increased chance of paper jams.
• Provide a sufficient clearances around the printer to ensure ventilation and ease of access. (See
section Clearance on next page).

(2) Places to avoid
Avoid installing the printer in locations exposed to:
• Direct drafts of hot or cold air.
• Direct drafts of outside air. (Avoid locations next to outside doors.)
• Sudden temperature or humidity changes.
• Any source of high heat, such as a radiator or stove.
• Excessive dust. Dust and smoke may cause contamination on the laser scanner window, causing
print quality problem.
• Vibration.
• Ammonia fumes or other harmful fumes. (In case of fumigating the room or saturate it with
insecticide, remove the printer first.)
• Avoid greenhouse-like rooms. (Because of sunlight and humidity.)
• Avoid enclosed spaces that block ventilation.
• Avoid sites more than 6,500 feet or 2,000 meters above sea level.
(3) Note on power
Use only the power source voltage conforming to the printer’s rated power voltage. Do not use
other power sources.
• Disconnect the printer from the power source before attempting removal or replacement of an
electrical component or a printed-circuit board.
• The printer should not be connected to a power source until the instruction is given to do so
when performing tests described in this manual.
• In connecting the printer power, exercise an extreme care in handling the power supply or any
other electric parts which may give an electric shock.
• Before performing maintenance or repair, power from both the power source and the associated
peripheral devices (computer, sorter, etc.) should be disconnected, unless otherwise specified.
• To avoid possible electrical shock, extreme caution must be exercised in handling the power
cord and any other electrical part.
• An easily accessible socket outlet must be provided near the equipment.
WARNING As the disconnect device is not incorporated in the printer’s AC primary
circuit, an easily accessible socket outlet must be provided near the equipment.

Observe the following precautions in removal and transportation of the printer.
• Be sure to repack the printer in its original carton.
• Do not leave the printer, toner container, process unit and other printer modules inside a vehicle
if the outdoor temperature is more than 25 °C. As unexpectedly high temperature may develop
inside when a vehicle is parked for a long period of time, the drum, toner container, process unit
and the supplies should be removed from the vehicle. The vehicle during transportation should
be parked in the shade or with the window open to allow minimum air circulation or the adequate
air conditioning should be made.
• Should the printer be left in a vehicle, it may not be exposed to the temperature change of more
than 7 °C within 30 minutes.
• Before removing the printer to a warm place, wrap it in a blanket, etc., before crating it. Allow
approximately two to three hours after having moved after uncrated. Failure to observe the
above may result in moisture condensation which will affect the performance of the printer.

1-5 About the toner container
1-5-1 Toner container
The printer should use a Kyocera TK-60/TK-60E toner kit. To ensure the high print quality and
long service life, the following handling precautions should apply:
CAUTION As the Ecosys printers are designed to ensure the optimum print quality when
used with Kyocera’s proprietary toner, Kyocera do not recommend to use any
refilled toner containers that may be available commercially. This is because
Kyocera have no means of control over how such refilled toner could affect the
print quality and the reliability of the printer.
(1) Toner container handling
To loosen and mix the toner inside before use, with the label side down, thoroughly shake the toner
container 1 (in the direction of the arrows) ten times or more.
Figure 1-5-1 Toner container handling
CAUTION The toner container is not designed for disassembly or refilling. Do not attempt
to disassemble or refill the toner container.
1
FS-1800/1800N | FS-3800/3800N
1-21
(2) Toner container storage
The toner contained in the container is susceptible to temperature and humidity. To ensure the high
print quality, store the toner container in a place that satisfies the following environmental conditions:
Temperature: −20 to 40 °C (−4 to 104 °F)
Humidity: 15 to 90 % RH
NOTE If the toner container is removed from the printer’s developer, put it in a
protective bag and keep it in a dark place.
CAUTION If the printer is shipped for return, etc., do not ship it with the toner container
installed. Remove the toner container from the developer and put in a plastic
bag and seal the plastic bag. Otherwise, toner may leak and contamination may
result in the printer.

(3) Paper feed unit
To avoid print quality problems due to paper dust and debris, clean the paper feed unit in the
following manner:
Pull the paper feed unit release lever 1 up and draw the paper feed unit all the way out until it
stops. Wipe the paper dust on the upper registration roller 2 and the paper ramp 3 using the
wiper cloth 4 included in the toner kit.
CAUTION Do not touch the transfer roller 5 (black sponge roller) when wiping the paper
ramp 3.
Area 6 below is factory-applied with lubricating oil. When cleaning the paper
feed unit 7, do not use alcohol to clean this area. If the oil is completely removed,
an incorrect action of the MP tray paper sensor (8, actuator) will result.

(4) Replacing the developer
To remove the developer unit from the printer for shipment or replacing to a new one, it should be
handled following the instructions below.
After the replacement, new developer needs to be initialized in manner explained in the section
Developer initialization (Feeding toner into the new developer) on next page.
Shipping the developer
The printer is supplied with a plastic bag that should be retained for future shipment of the developer.
To pack the developer 1 in the packing carton, first flap down the magnet roller protective cover
2. Put the developer 1 into the supplied plastic bag 3. Put the developer 1 on the developer
install position 4 of packing carton.

(5) Developer initialization (Toner install mode)
The new developer unit is shipped from the factory with no toner contained. The developer can be
automatically replete with toner when a toner container is installed onto it and the printer is turned
on. However, because the toner reservoir in the developer has a large capacity, it requires a lengthy
period of time until a substantial amount of toner has been fed to get the printer ready. (A new
developer needs approximately 100 g for triggering the sensor inside.)
A great many seconds of time for this is greatly deducted by using the service menu in the printer’s
mode select routine as accessed by its operation panel. Follow these steps to use this feature, top to
bottom (For details, refer to section 2-3 Using the operator panel on page 2-19).

(6) Developer refreshing mode
This mode is used to eliminate light printing problems. Once activated, the toner in the developer
unit is enforced to be sent onto the drum unit, collected back in the waste toner bnottls. At the same
time the new toner is fed in the developer so that the developer unit is refilled with new toner. Once
activated, the printer will keep engaged in this mode and be running for an average of 60 minutes.
NOTE The amount of the (old) toner replaced and collected in the waste toner bottle
will be approximately 100 g. The waste toner bottole consequently become full
and must be replaced with a new one.
Perform in sequence: Display shows:
1 Turn printer power on.
2 Make sure the printer is Ready.
(Connect the printer to the computer using the parallel interface.
3 At the DOS prompt, send the following command to the printer:
>ECHO !R!EXTP 7,92;EXIT;>PRN
4 Turn printer power off, then on. The toner refreshing mode will
begin. The old toner will be rejected in the first approximately 20
minutes, followed by another 40 minutes interval in which the new
toner is fed in the developer unit.
5 Check that the display reverts to Ready.
(If the display shows “Call service person99”, refer to section 6-1-2
Diagnostic (Service error messages) on page 6-11.
6 Print a page to check the print density.

(7) Drum cleaning mode
This mode enforces the printer to rotate the drum against the cleaning roller inside the drum unit for
a predetermined period of time. The cleaning roller then removes dust and debris that may have
resulted from dew condensation on the drum.
The printer automatically activates the drum cleaning mode based on the environmental conditions
as the temperature/humidity sensor detects. The time required to complete the drum cleaning mode
varies depending on the current setting for the sleep timer and will be deactivated during the developer
initialization.
The drum cleaning mode is also activated manually by following the steps below:
Perform in sequence Display to show Remarks

4-1 Electrophotographic system
Electrophotography is the technology used in laser printing which transfer data representing texts
and graphics objects into a visible image which is developed on the photosensitive drum, finally
fusing them on paper using the light beam generated by a laser diode.
This section provides technical details on the printer’s electrophotography system.
4-1-1 Electrophotographic cycle
The electrophotographic system of the printer performs a cyclic action made of six steps as follows.
Each step is technically explained in the following sections.

Amorphus-silicon drum
The printer use the long lasting amorphous silicon drum. The drum surface is a composite of five
substances coated in five layers as shown below.
Figure 4-1-3 Amorphus silicon drum
The primary and secondary layers are for protecting the amorphous silicon layer underneath. The
amorphus silicon layer is of photoconductive, meaning it can be electronically conductive when
exposed to a (laser) light source to effectively ground electrons charged on its outer surface to the
ground. This layer is approximately 9 µm thick.
The carrier block layer lies between the amorphous silicon layer and the aluminum base cylinder
and prevents the backward electron flow, from the base cylinder to the drum’s outer surface, which
might give adverse effect (possibly “ghost”) on the print quality.

Charging the drum
The following shows a simplified diagram of the electrophotographic components in relation to the
engine system. Charging the drum A is done by the main charger wire B.
Figure 4-1-4 Charging the drum
As the drum A rotates in a “clean (neutral)” state, its photoconductive layer is given a uniform,
positive (+) corona charge dispersed by the main charger wire B. The grid C regulates the main
charging potential so that it is evenly and stably dispersed over the drum A at a constant voltage
level.
Due to being high-voltage scorotron charging, the main charger wire B can get contaminated by
oxidization after a long run. Therefore, it must be cleaned periodically from time to time using the
method explained in chapter 3, page 3-9. Cleaning the main charger wire B prevents print quality
problems such as black streaks.

The charged surface of the drum A is exposed to the laser beam scanning from the laser scanner
unit B.
Figure 4-1-5 Exposure
The polygon motor C (with polygon mirrors) revolves to reflect the laser beam over the drum A.
Lenses D and diversion mirror E are housed in the laser scanner unit B. These lenses adjust the
diameter of the laser beam (670 nm wavelength) so that the laser beam effectively focalizes on the
drum A surface.

6 Secondary f-theta lens The primary (above) and secondary f-theta lenses equalize focusing
distortion on the area on the drum closer to the edge. The effective
length of line (A, B in the figure below) the laser beam draws on
the drum becomes longer as the laser beam hits closer to the drum
edge. In the figure 4-1-7 below, distances represented by A and B
are not the same (A > B) until the f-theta lenses are provided between
the polygon mirror and the drum (A = B).
7 Diversion mirror Diverts the laser beam vertically onto the drum. Note the diffused
laser beam finally pinpoints on the drum.
8 Protective glass Prevent dust, debris, etc., from entering the scanner assembly.
9 Sensor mirror Bends the very first shot of a laser scan towards the pin photo sensor
(below).
0 Pin photo sensor When shone by the sensor mirror above, this pin photo sensor
generates a trigger signal.

Drum surface potential
The laser beam is continually switched on and off depending on the print data. It is on for a black
(exposed) dot and off for a white (blank) dot. Since the drum surface is evenly charged, whenever
it is illuminated by the laser beam, the electrical resistance of the photoconductor is reduced and the
potential on the photoconductor is also lowered. Resulted on the drum surface is an electrostatic
image which represents the data to print. Note that the area to be printed black has the low potential,
constituting a “positively exposed” image.

The latent image constituted on the drum A is developed into a visible image. The developing
roller B contains a 4-pole (S-N-S-N) magnet core C and an aluminum cylinder rotating around
the magnet core C. Toner attracts to the developing roller B since it is powdery ink made of black
resin bound to iron particles. Blade D magnetized by magnet E is positioned approximately 0.3
to 0.4 mm above the developing roller B. It constitutes a smooth layer of toner in accordance with
the revolution of the roller.
Figure 4-1-10 Development
The developing roller B is applied with the AC-weighted, positive DC power source. Toner F on
the developing roller B is given a positive charge. The positively charged toner F is then attracted
to the areas of the drum A which was exposed to the laser light. (The gap between the drum A and
the developing roller B is approximately 0.3 mm.) The non-exposed areas of the drum A repel the
positively charged toner as these areas maintain the positive charge. The developing roller B is
also AC-biased to ensure contrast in yielding by compensating the toner’s attraction and repelling
action during development.

A toner sensor is provided within the developer. As the toner supply from the toner container
dwindles and the toner level lowers in the reservoir, the sensor translates it into an electrical signal
through its diaphragm, urging the toner motor to feed more toner.

(4) Transfer
The image developed by toner on the drum A is transferred onto the paper because of the electrical
attraction between the toner itself and the transfer roller B. The transfer roller B is negatively-
biased so that the positively-charged toner is attracted onto the paper while it is pinched by the
drum A and the transfer roller B.
Figure 4-1-12 Transfer
The nominal transfer bias is set to approximately -2.3 kV (limit) with the -65 µA current. Since the
ideal potential of the transfer bias depends on the thickness of paper, the bias is raised to approximately
-2.6 kV/-65 µA for thicker paper. On the other hand, the bias current is reduced to -2.1 kV/-65 µA
for thin paper.

(5) Fusing
The toner on the paper is molten by heat and pressed into the paper as it passes between the heat
roller A and the press roller B in the fuser unit.
Figure 4-1-13 Fusing
The heat roller A has a heater (infrared) lamp C inside which continuously turns on and off by the
thermistor to maintain the constant temperature on the heat roller A surface. The fusing temperature
is also controlled based on paper types. See the table in the figure above.
The heat roller A is florin coated by to prevent toner from accumulating on the roller after a long
usage. Care must be taken while handling the heat roller A not to scratch the roller surface as
doing so may result in quality problems.
The heat roller A has four scraping claws (Separators) D which are continuously in contact with
its surface. These claws prevent the paper on which toner has been fused from being wound around
the heat roller A causing paper jam.
The press roller B is made of the heat resistant silicon rubber. This roller is used to strongly press
the paper towards the heat roller A by means of coil springs.
The temperature of the heat roller A is constantly monitored by the engine board using the thermistor
and triac. Should the temperature of the heat roller A exceed the predetermined value, the thermal
cutout is activated to effectively disconnect the heater lamp C from power.

(6) Cleaning
After the transferring process, the drum needs to be physically cleaned of toner which is residual
after the development process. The cleaning blade A is constantly pressed against the drum B and
scrapes the residual toner on the drum off to the cleaning roller C. The cleaning roller drives the
toner to the cleaner screw D at one end of which the waste toner bottle is connected to collect the
waste toner.
Figure 4-1-15 Drum cleaning and erasing static charge
After the drum A is physically cleaned, it then must be electrically cleaned to neutral state. This is
necessary to erase any residual positive charges, ready to accept the next uniform charge. The
residual charge is canceled by exposing the drum A to the light emitted from the eraser lamp
[board] E (See figure 4-1-15 above.) in the similar manner as described on page 4-6. This lowers
the electrical conductivity of the drum A surface making the residual charge on the drum A
surface escape to the ground.

4-2 Paper feeding system
The paper feeding system picks up paper from the paper cassette, MP tray, or if installed, the paper
feeder PF-60, feeds it in the printer and delivers in the output tray. Paper is feed at the precise
timing in synchronization with data processing. The paper feeding system finally delivers the printed
page to either the face-down or face-up output tray as manipulated by the user.
The figure below shows the components in the paper feeding system and the paths through which
the paper travels. The sensors, clutches, solenoids, motor etc., are described in the following pages.

Eraser lamp control circuit
CPU (U201) turns on its #59 pin to H and turns Q215 and Q214 on. Current flows through Q214
and R249, then the eraser lamp, activating the lamp. Current also routes through R251 and R252 as
bled by R251. Point A below is approximately 14.5 V when the eraser lamp is normal. If the eraser
lamp blows out or the connector is not fitted, current goes through only R251 and R252, subsequently
the potential at point A is as high as approximately 24 V. Difference in the potential at point A
where the eraser lamp is normal or not is automatically detected as an error. When anomaly is
detected with the eraser lamp, the detector circuit turns Q216 on and turns ERDEAD* at #60 pin of
CPU (U201) to L. This in turn causes CPU (U201) to determine that the eraser lamp is faulty,
displaying Call service personE5.

Toner motor control circuit
As TMOTON at #15 of gate array (U204) turns to H, Q218 and Q217 turn on, and +24 V reaches
Q217, R265 and the toner motor, finally driving the toner motor.
If the toner motor is overloaded by some reasons, an overcurrent may flow through the toner motor
beyond the predetermined level, turning Q220 on. Q220, when turned on, causes the current from
the +24 V power supply to flow through Q217, Q220, R267, R268, and to the ground. Consequently,
approximately 3.9 V (H) develops at point A, as limited by the combination of R267, R268, and
DZ206. This voltage is used as TNMOC - toner motor error - which is applied to #17 of CPU
(U201). Thus, CPU determines the toner motor error and lets Call service person E9 be
indicated.

Heater lamp control circuit
The heater lamp control circuit turns the heater lamp on and off which is located coaxially inside
the heat roller. The surface of the roller maintains the constant temperature needed to permanently
fuse the toner on paper.
The heater lamp is directly fed with AC primary power (120 V or 220 - 240 V) which is supplied
from the power supply unit.

As change in temperature is detected by the thermistor, CPU U201 adjusts the voltage that is
resultant of change in temperature, given at pin #3 (THERM) to keep the temperature as constant as
possible. This voltage is used to continuously switch the fuser lamp on and off. If pin #4 (HEATON)
of the engine gate array U204 is H level, transistor Q204 (pin #2) turns on, the photo coupler (PC)
on the power supply unit turns on, and the triac (TRC) turns on, consequently the heater lamp is AC
powered and lights. The heater lamp continuously turns on and off to maintain the temperature on
the heater roller at approximately 185*1/200*2 °C (Normal paper, A4), 175*1/190*2 °C (Thin paper,
A4), and 190*1/205*2 °C (Thick paper, A4) for printing and approximately 95 °C at standby (Ready).
Refer to section Fusing on page 4-15. *1: FS-1800/1800N *2: FS-3800/3800N
Abnormal temperature detection circuit
The thermal cutout device which is connected in series with the heater lamp, constitutes the the
abnormal temperature detection circuit including of comparators U205-2, R217, R219, etc. Pin #5
of the comparator U205-2 is continuously given with the voltage by resistors R217 and R219,
which simulate the voltage given if an abnormally high temperature develops. Pin #6 receives the
voltage the thermistor detects. For instance, the heater lamp happens not to switch off, the voltage
the thermistor gives at pin #6 will become unusually high, and as soon as it exceeds the voltage at
pin #5, pin #7 of the comparator U205-2 output changes to L level. This in turn turns transistors
QA201B and QA201A on, and turns QA201A (pin #6) to L level. Since pins #6 of the transistor
QA201A and #2 of transistor Q204 are connected to each other, pin #4 of the engine gate array
U204, even though it is currently at H level, is enforced to be H level, effectively disabling the
heater lamp. Pin #7, the output from comparator U205-2, changes to L. Then, it is output to #63 of
CPU (U201) which in turn determines that an unusual temperature has developed in the fuser,
indicating Call service personE4.
Thermistor blown-out detection
The thermistor is monitored by the combination of comparator U205-1, R233, and R238. Extremely
low potential is applied to pin #3 of U205-1 by means of R233 and R238. Whereas, pin #2 is
applied with the voltage the thermistor detects. In normal state, as the heater lamp glows, the voltage
detected by the thermistor is greater than the potential at #3 of U205-1, making the U205-1 output
to L and sent to #54 (THDEAD) of CPU.
When the thermistor has blown, pin #2 of U205-1 becomes zero which is well lower than the
potential at pin #3 of U205-1, the comparator output becomes H, delivering THDEAD at pin #54 of
CPU. CPU uses this signal to determine that the thermistor is faulty and displays Call service
personE4.

(3) Sensor board
Paper gauge sensing circuit
Paper gauge operates in four levels of paper remaining in the cassette. The height of the paper stack
in the paper cassette changes the angle of the actuator. At the end of the actuator is a reflecting
mirror which reflects or interrupts the light emitting from photointerruptor sensors PH702 and
PH703 accordingly.
These two sensors generate four digital signals which will be digital-analog-converted and input to
A/D port of CPU. CPU then issues signals according to the level of the analog signals. The resultant
signals are used to monitor the amount of paper in the cassette through the network management
utilities.

Interlock circuit
Figure 4-3-11 Interlock system
The interlock circuit is constituted by SW702, the top cover/paper feed unit interlock, and SW703,
the side cover interlock, both mounted on the sensor board. These switches are controlled by the
actuator which is mechanically activated by the projection on the top cover and the feed unit.
SW703 and SW702 are connected in series to the +24 V power. Physically opening the top cover,
side cover, or the paper feed unit will disconnect the +24 V power, signaling the status to the engine
board. The top cover switch (SW701) serves only the top cover.

Paper size detecting circuit
The three paper size switches (SW1, SW2, SW3) are activated according to the positioning of the
paper size dial on the paper cassette. An analog signal is generated by the combination of the paper
size switches, which are put in comparison with the voltage/paper size table referenced by the
paper size detecting circuit. The paper size is detected.

The paper size dial has predetermined patterns of activating the paper size switches using concaves
and convexes according to paper sizes. SW1, SW2, and SW3 produce corresponding signals for
paper sizes. These patterns are translated into analog voltages and sent to the engine board on a
single line. The signals are analog-digital-converted on the engine board.

Check the developer.
• Check that the developer is inserted correctly. See page 5-4.
• Check that the toner on the magnet roller surface. See page 5-4.
Check the transfer bias potential.
• Check the transfer bias output on the high voltage unit. This requires removal of the left cover and
the test equipment. Replace the high voltage unit if high voltage potential is not available on the
board. See page 5-25.
Check the laser scanner unit.
• The scanner components within the scanner may be disordered. Replace the laser scanner unit.
See page 5-37.

Check the main charger unit
• Open the printer side cover and check that the drum unit is correctly seated. Check for poor
contact of the main charger terminal between the main charger unit and the drum unit.
Check the drum bias.
• Make sure the bias from the high voltage unit correctly arrives at the drum unit.
Check high voltage potential at the high voltage unit.
• Check the high voltage output on the high voltage unit. Replace the high voltage unit if high
voltage potential is not available on the board.
6-40FS-1800/1800N | FS-3800/3800N
(3) Dropouts
Note the spacing of the defects. Refer to Repetitive defects gauge. See page 6-47.
• If the defects occur at regular intervals of 39 mm, the problem may be the damaged developing
roller (in the developer). Replace the developer. See page 3-13.
•If the defects occur at regular intervals of 94 mm, the problem may be the damaged drum (in the
drum unit). Replace the drum unit. See page 5-12.
•If the defects occur at regular intervals of 72*1/94*2 mm (heat roller) or 79 mm (press roller), the
problem may be the damaged fuser unit. Replace the press roller or heat roller. See page 5-34 or 5-
36. *1: FS-1800/1800N *2: FS-3800/3800N
Check paper property.
• Paper with rugged surface or dump tends to cause dropouts. Replace paper with the one that
satisfies the paper specifications.
Check the transfer roller installation.
• The transfer roller must be supported by the bushes at the both ends. Clean the bush to remove oil
and debris. Replace the transfer roller if necessary. See page 5-17.
Check the transfer bias potential.
• Check the transfer bias output on the high voltage unit. This requires removal of the left cover and
the test equipment. Replace the high voltage unit if high voltage potential is not available on the
board. See page 5-25.
ABC123
6-41FS-1800/1800N | FS-3800/3800N
(4) Black dots
Note the spacing of the defects. Use the Repetitive defects gauge. See page 6-47.
• If the defects occur at regular intervals of 94 mm, the problem may be the damaged drum (in the
drum unit). Replace the drum unit. See page 5-12.
• If the defects occur at random intervals, the toner may be leaking from the developer and drum
unit. Replace the developer and drum unit. See page 5-4 and 5-12.
(5) Black horizontal streaks
Check the drum unit’s ground.
• The drum axle in the drum unit and its counter part, the grounding tab in the printer, must be in a
good contact. If necessary, apply a small amount of electro-conductive grease onto the tab.
The drum may be defective.
• Replace the drum unit. See page 5-12.

(6) Black vertical streaks
Contaminated main charger wire.
• Clean the main charger wire by pulling the green colored cleaning knob in and out several times.
See page 3-9.
Check the drum surface for a streak of toner laying lengthwise.
• A streak of toner remaining on drum after printing means that the cleaning blade (in the drum unit
) is not working properly. Replace the drum unit. See page 5-12.
Defective magnet roller (in the developer).
• Replace the developer. See page 5-4.
ABC123
6-43FS-1800/1800N | FS-3800/3800N
(7) Unsharpness
Check paper for property.
• Paper with rugged surface or dump tends to cause unsharp printing. Replace paper with the one
that satisfies the paper specifications.
Check the transfer roller installation.
• The transfer roller must be supported by the bushes at the both ends. Clean the bush to remove oil
and debris. Replace the transfer roller if necessary. See page 5-17.
Check the transfer bias potential.
• Check the transfer bias output on the high voltage unit. This requires removal of the left cover and
the test equipment. Replace the high voltage unit if high voltage potential is not available on the
board. See page 5-25.
Check EcoPrint setting.
• The EcoPrint mode can provides faint, unsharp printing because it acts to conserve toner for draft
printing purpose. For normal printing, turn the EcoPrint mode off by using the operator panel. For
details refer to the printer’s User’s Manual.
6-44FS-1800/1800N | FS-3800/3800N
(8) Gray background
Check the print density setting.
• The print density may be set too high. Try adjusting the print density using the Remote operation
panel utility. For details refer to the printer’s User’s Manual.
Check the surface potential of the drum (in the drum unit).
• The drum potential should be approximately 230±15 V. This may vary depending on production
lots. Measurement is possible only by using the jig and tool specifically designed for this purpose.
The drum unit will have to be replaced if it bears values far out of the allowable range.
Check the grid.
• Clean the grid by grid cleaner. See page 3-9.
The developing roller (in the developer) may be defective.
• If a developer which is known to work normally is available for check, replace the current developer
in the printer with the normal one. If the symptom disappears, replace the developer with a new
one. See page 5-4.

• Dirty edges and back of the paper can be caused by toner accumulated on such parts as the paper
chute, paper transportation paths, the bottom of the drum and developer, and the fuser unit inlet.
Clean these areas and parts to remove toner.
Check the transfer roller.
• If the transfer roller is contaminated with toner, clean the transfer roller using a vacuum cleaner;
or by continuously printing a low-density page until the symptom has faded away.

The printer can print two different types of the status page—the user (normal) status page and the
service status page. This section exclusively describes information obtainable with the service status
page. For information on the user (normal) status page, refer to the printer’s User’s Manual.
Information on the service page include various settings for the printer, service statistics, etc. To
print a service status page, proceed as follows:
Printing the service status page
To print a service status page, using the MENU key. Or, have a PC running MS-DOS and proceed
as follows:
1. Connect the printer to the PC via the parallel interface.
2. Ensure that the printer is ready to print.
3. At the DOS prompt, type:
echo !R! STAT 1; EXIT; >lpt1:
The service status page is printed. (If you omit ‘1,’ a user status page is printed.)

Parallel interface
The printer uses a bidirectional parallel interface for high-speed data transmission for the host
computer. This interface includes the buffers which are compatible with the IEEE 1284 standards.
The parallel interface provides support for the ECP and nibble modes in this standards. The parallel
interface mode can be changed by commanding Prescribe commands on a PC.
Selecting the parallel interface mode
To change the parallel interface mode, a PC running MS-DOS is needed. Connect the printer to the
PC via the parallel interface. Then, at the DOS prompt, type a FRPO O0 (the letter O and the
number zero) command as follows depending on the desired parallel mode:
To set the parallel interface mode... Type at the DOS prompt...
Normal echo !R! FPRO O0, 0; EXIT;>lpt1:
High-speed echo !R! FPRO O0, 1; EXIT;>lpt1:
Nibble* echo !R! FPRO O0, 5; EXIT;>lpt1:
Automatic echo !R! FPRO O0, 70; EXIT;>lpt1:
*: Factory-set default.

Parallel interface signals
The following table provides details for the signals used on the printer’s parallel interface. Note
descriptions in [ ] are for high-speed mode of the parallel interface.
Signal Meaning
A negative-going Strobe* pulse causes the printer to read and latch
the data on the Data 0 [1] to Data 7 [8] signal lines.
These eight signals form the data byte sent from the host computer to
the printer. Data 7 [8] is the most significant bit and Data 0 [1] is the
least significant bit.
This signal is returned to the host computer. This negative-going pulse
acknowledges the previous character received by the printer.
Acknowledge* pulses are sent only when Busy is low.
This signal is returned to the host computer. This signal is high when
the printer is busy and low when it is able to accept more data. Every
high-to-low transition is followed by an Acknowledge* pulse.
This signal is returned to the host computer. This signal goes high
when the printer runs out of paper.
This signal is returned to the host computer. This signal is high when
the printer is on-line and low when the printer is off-line. It goes low
when the upper unit is raised, or when the GO key is pressed to set the
printer off-line.
Note: The Paper Empty and On-Line signals are not used unless enabled
by the FRPO command (O2 parameter).
This signal is used in the Epson version of the Centronics interface to
receive a carriage return. In high-speed mode, it is used as an interrupt.
This line is connected to the printer’s +5 V DC line (+5 V ±0.5 V, 500
mA maximum, fused).
This signal is used in the standard Centronics interface to enable the
computer to reset the printer. It is ignored by the printer.
When the high-speed parallel line control is on (FRPO O2 = 2), this
line returns error status to the host computer.
This signal line is not used.
This signal is high when the printer’s power is on.
This signal is used in some versions of the Centronics interface to
enable the computer to force the printer on-line. In high-speed mode,
it is used as an interrupt.

Serial interface
The printer is equipped with a serial interface connector. The device responsible for controlling the
serial interface is integrated in the gate array in the controller system. The serial interface supports
protocol of RS-232C. A 25-pin D-sub connector is used for the serial interface.
RS-232C interface voltage levels
The voltage levels of the RS-232C signals conform to EIA RS-232C specifications. FALSE is from
3 volts to 15 volts. TRUE is from -3 volts to -15 volts. Voltages between -3 volts and 3 volts are
undefined.
Connector configurations
The printer uses a DB-25 connector for the serial interface. Depending on the computer configurations
for serial interface, use either of the appropriate configurations.
Signal Meaning
FG (Pin 1) This pin is connected directly to the printer frame.
TxD (Pin 2) This output carries asynchronous data sent by the printer to the computer.
It is used mainly in handshaking protocols.
RxD (Pin 3) This input carries serial asynchronous data sent by the computer to the
printer.
RTS (Pin 4) This output is always held high (above 3 V).
CTS (Pin 5) Unused.
DSR (Pin 6) Unused.
SG (Pin 7) All signals can transmit between the printer and the host computer to send
each signals with a signal ground.
+5V (Pin 12) Power supply for barcode reader. (Maximum 500 mA)
DTR (Pin 20) This output is used as a buffer nearly-full handshake line. It is held high
(above 3 V) when the buffer can accept more data.
