II. READING SYSTEM

1. Reading Unit The sectional view of the reading units is

shown below. The upper and lower reading units have the same configuration but the different shapes for the reading cover each.

CIS unit

Reading cover

Figure 2-201

The upper reading unit reads the back

side of the documents and the lower reading unit reads the front side of the documents. This configuration enables the machine to read both front and back sides of a docu-ment using a single scan.

The read image data are sent to the image processing section of the control PCB.

The reading unit consists of CIS unit,

and reading cover. The CIS unit consists of CIS PCB, lens

array, LED (R/G/B), light guide, and case. The reading glass and white reference

sheet are mounted on the reading cover.

Photosensitive pixels are mounted on the CIS PCB with a density of 600 dpi in a line. The effective reading width is 216 mm, and the number of effective picture elements is 5104.

A set of three basic color LEDs, red, green, and blue (RGB), is mounted only on the one side. This single-side illumination causes a shadow on a document, which may effect on the image data quality.

In the binary or grayscale modes, image data are read with composite light generated by lighting the RGB LEDs at the same time. In the color mode, the LED is successively lit, and reads image data with each color. As documents are being fed at regular speed while image data are read, the reading po-sitions of RGB are shifted slightly.



2. Shading This section explains the reading

mechanism of the white reference sheet for determination of the shading correction

value. The sectional view of the reading unit is

shown below.

Whitereferencesheet

Whitereferencesheet

Figure 2-202

This machine can read the white refer-

ence data at the document reading position, unlike other scanners having the black background color, since its background color is white. Therefore, there is neither need to feed the shading sheet nor to move the internal white reference sheet or the reading units.

For example, when the lower reading unit reads the white reference data, the LED emitted from the lower unit is reflected from the white reference sheet on the upper unit to be input to the sensor on the CIS PCB.

Since the white reference sheet is placed under the reading glass, feeding document does not cause smudges on it.

When this machine is turned ON or starts scanning, it reads the white reference data to determine the shading correction value.

However, the slightly different optical paths to the light receiving element are used for the actual document and the white ref-erence sheet. Therefore this machine needs fine adjustment of the shading correction value using the service mode and the shading sheet. This fine adjustment is nec-essary after replacing the reading unit or after replacing the control PCB recording the shading correction value.



III. FEED SYSTEM

1. Document Feed The sectional view of the document feed

system is shown below.

7 Eject roller (drive) 8 Eject roller (follower) 9 Detection point of document sensor 10 Detection point of registration sensor 11 Upper reading unit (back reading) 12 Lower reading unit (front reading)



1) Feed path The feed path of this machine is a straight path that is horizontal to the eject roller including the pickup tray to the reading section. The pickup roller is not mounted. The leading edge of the loaded document is detected by the document sensor and touches the feed roller and the separation pad. The document pressure lowers, fol-lowing the registration roller, and presses the document against the feed roller. Once the machine starts scanning, it activates the rollers to feed the document inside. The document passes through the regis-tration roller, the reading units, and the eject roller and is ejected to the outside of the machine. This machine does not have an eject tray.

2) Drive

The feed motor drives the feed roller and each drive roller. The rotational speed of the feed motor is determined by scan conditions. To provide space between the leading edge of a document and the trailing edge of the next document, the drive speed of the feed roller is slightly lower than the drive speed of the registration roller and eject roller. If it is left as it is, the document is braked when it touches the feed roller and the registration roller, and therefore, a one-way clutch is built into the gear used in the feed roller drive system to follow the drive speed of the registration roller.

3) Separation Separation of the documents is performed by the separation pad. Double feeds and pickup errors are prevented by optimizing the shape of the separation pad and fric-

tion against documents. However, if the document setting method is incorrect, the contact between the document and the separation pad be-comes poor and double feeds or pickup errors tend to occur easily. For details on the document setting method, refer to the user manual or "CHAPTER 1 GENERAL DESCRIPTION, III. USER OPERATION".

4) Sensor For document detection, the document sensor is mounted on the document set-ting section and the registration sensor is mounted on the registration roller section. They are used for feed control and feed error detection



2. Feed Error Paper Jam Detection

Paper jams are detected by the regis-tration sensor. The types of the document jams are described as follows. 1) Pickup Delay Jam (Pickup Error) The leading edge of the document was not

detected by the registration sensor within the specified time after the machine starts scanning.

2) Early Reach Jam The leading edge of the following docu-

ment was detected after the trailing edge of the document was detected by the registration sensor before the document has been fed for a specified length.

3) Residual Jam The trailing edge of the document was not

detected even though the document has been fed for the maximum specified length after the leading edge of the document was detected by the registration sensor.

4) Fast Feed Jam The trailing edge of the document was

detected after the leading edge of the document was detected by the registration sensor before the document has been fed for the minimum specified length.

5) Non-removal Jam The machine starts scanning while the

document is detected by the registration sensor and still remains inside this ma-chine.

Double Feed Detection A double feed is detected by the

document length detection by the registra-tion sensor.

The first document length of the scanned batch is used as a reference to detect the document length. The 35 mm or more difference from the standard is inter-preted as a double feed.

Analog signals proportionate to the density of each picture element are output to the analog processor on the control PCB from the CIS unit. The resolution of the output data is either 300 dpi or 600 dpi ac-cording to the user settings.

The analog processor carries out offset adjustment, gain adjustment, and A/D con-version. Analog signals are converted into 12bit digital signals in the analog processor. Then the image data is transferred to the scanner controller and converted from 12 bits to 8 bits.

After that, the image data is output to the computer through USB interface. The computer-side connector of the USB cable used for this machine is of USB 2.0 standard A type, and the device-side connector is of USB 2.0 mini B type. The signal speed supports USB2.0 Hi-speed.

The computer performs the image processing according to the user settings after the signal rearrangement, resolution conversion and shading correction.

Since this machine has a white back-ground, black border removal and punch hole removal are not necessary.



V. POWER SUPPLY

1. Power Supply USB bus power is used to supply power

to this machine. This is a method of sup-plying power from the computer through a USB cable.

The rated power of a cable is 5 VDC, 0.5 A.

When a power supply cable is con-nected and the pickup tray is opened, the tray switch is pressed and the power is switched ON. When the pickup tray is closed, the power is switched OFF.

Each voltage required inside is gener-ated on the control PCB.

The main parts that consume electricity

in this machine are the elements of the ICs, etc. on the control PCB, the upper and lower CIS units and the feed motor. The required current value for the feed motor changes according to the load during feeding. To use a special method of feed motor control and power supply if the load increases, the fol-lowing components are provided: 1) Feed motor with an encoder 2) Electric double layer capacitor (EDLC)

The encoder detects that the feed load

increases and the number of revolutions decreases, the pulse supplied to the feed motor changes. If the current is insufficient, the capacitor is discharged. If the capacity of the capacitor becomes insufficient, feeding and reading stop and the capacitor is charged. When it is charged again, the feeding and reading begin. However, if the prescribed rotational speed is not reached even when an electric current is added from

the capacitor, the rotational speed is re-duced and the timing of reading is changed accordingly.

The reading cannot be started until the electric double layer capacitor is sufficiently charged. If the power is switched ON when the capacitor is fully discharged, charging takes approx. 15 seconds. Since it is dis-charged when the power is OFF, reading cannot be performed for a period of time of approx. several to 15 seconds after the power is switched ON.

B. Adjustment 1. Registration (Auto)

This mode performs adjustments on a reading-start position and reading-end posi-tion for feed direction automatically.

If the leading- and trailing-edge posi-tions of a scanned image are improper, perform this adjustment.

Also perform this adjustment after re-placing or reassembling a registra-tion-related part such as the reading unit or the control PCB on which a registration sensor is installed.

This mode can be used together with other adjustment items. For details, refer to “All”.

Adjustment sheet

The dedicated sheet is required to execute this mode. However, you can create the sheet by drawing a black line on available paper, so it is not specified as a service tool. Prepare it for yourself. The sheet is required:

1) The material may be normal white copy paper, recycled paper or shading sheet (TKM-0326/0332) that is used in the next section.

Note: If the shading sheet is used, it can be shared with “Light”.

Note: Do not use adjustment sheets with black edges, which are used for other DR scanners. Otherwise, adjustment cannot be performed correctly.

2) For four corners of the leading and trailing edges, the black part must be 5 mm long and 20 mm wide.



3) Paper size is basically A4 size or LTR size, and the above-mentioned shading sheet, and must have the following range: Width: 200 to 220 mm; Length: 130 to 297 mm.

4) To cause neither jams nor skews. Example: Blacken the leading edge of a A4

size or LTR size paper with a black pen. Use the sheet after the ink has dried. Do not use a pencil.

The shading sheet may be used.

Note: If it stops in the middle when using A4

size or LTR size paper due to the computer specifications, set to half the size. Note that you should cut that paper perfectly straight without any slant.

Operation Procedure 1) Clean feed path, roller, and reading glass. 2) Load a piece of the registration sheet you

prepared. Make sure to set the document guides to fit the sheet to prevent skews.

Note: The black edge needs to be detected as the leading edge of the sheet with the front side sensor. Load the sheet with the black-lined side facing down, considering this black edge of the sheet is the top of feed. Do not set extra sheets.

2. Registration (Manual) Normally, registration adjustment is

performed in automatic mode, but this manual adjustment is used to fine adjust results of automatic adjustment. Note that it does not reduce variations in the registration position.

Adjustment sheet

Use the same sheet as the scale pa-rameter adjustment sheet. For details, refer to the “Registration (Auto)” section.

Operation Procedure 1) Perform the operation procedure in the

“Registration (Auto)” section. 2) The value adjusted at the Registration

(Auto) is displayed in the data box for the leading edge.

Figure 5-227

3) When the [Edit] button on the information

screen is selected, the value is displayed validly and can be modified.



4) The value to adjust is changed by directly entering in the data box or by using the scroll arrows. This amount of additional change is added to the value previously set by the automatic adjustment. For example, if the value is already [0.4], then enter [-0.6] if you want to add 1mm to make the reading start 1mm earlier, or enter [1.4] if you want to subtract 1mm.

Note: The input values range from -5.0 to 5.0.

5) If the [Apply] button is selected, the value

is saved, and if the [Cancel] button is se-lected, it is not saved.

Figure 5-228

6) Execute a scan test and check the posi-

tion.

3. Light This mode performs fine adjustments on

the shading correction values since the reading point differs between the white ref-erence sheet inside of the reading unit and the actual document.

If the scanned image quality is degraded, perform this adjustment. Also perform this adjustment after replacing the reading unit or after replacing the control PCB recording the adjustment data.

This mode can be used together with other adjustment items. For details, refer to “All”.

Adjustment sheet

The shading sheet is required to execute this mode. Use TKM-0326 or TKM-0332, which is the same shading sheet as the one used for the P-215 or others. Do not use a sheet with any dirt or creases.

Note: Shading sheet with a black line for “Registration adjustment” can also be used.

Operation Procedure

1) Clean feed path, roller, and reading glass. 2) Open the document guides fully extended,

then load a shading sheet you prepared to fit the width between the document guides.

Note: Do not set extra sheets.

Figure 5-229



3) On the service screen, select [Light].

Figure 5-230

4) The adjustment starts automatically. Thesheet is fed, and a progress screen isdisplayed.

Figure 5-231

5) Even after the sheet has been ejected, thedata may be processed inside the ma-chine. The progress screen disappears,and a caution screen is displayed. Do notturn OFF the machine or perform any op-erations until the caution screen disap-pears.

Figure 5-232

6) After the adjustment is complete, the cau-tion screen disappears.



4. Regist sensorThis mode is used to adjust the initial

value of the quantity of light received when the document is not set at the sensor section so that the registration sensor operats cor-rectly.

The value performed at the factory is set when the sensor is shipped from the factory, but the adjustment is carried out if the regist sensor does not detect a document correctly because the ambient amount of light is very different and so on. Also run this mode after replacing the control PCB on which the sensor is installed.

This mode is included in “All” described later.

Operation Procedure 1) Clean the surface of the light guide for the

registration sensor.Note: Do not set the adjustment sheet. 2) On the Adjustment screen, select [Regist

sensor].

Figure 5-233

3) The adjustment starts automatically andends instantaneously.

Figure 5-234

Note: A progress screen is displayed, but it cannot often be confirmed because it is displayed instantaneously.



5. All In this mode, “Registration (Auto)”,

“Light” and “Regist sensor” described above are performed continuously. The purpose and timing to perform each adjustment are discussed in the corresponding section. Adjustment sheet

Use a document on which black lines are written as a shading sheet. (For details on how to write black lines, refer to

Adjustment sheets in “Registration (Auto).”

Operation Procedure

1) Clean feed path, roller, and reading glass. 2) Load a prepared adjustment sheet. Load

the sheet with the black-lined side facing down. Insert them properly not to cause skew.

Note: Do not set extra sheets.
