G. Variable Resistors (VR), Light-Emitting Diodes, and CheckPins by PCB

Of the variable resistors (VR), light-emitting diodes (LED), and check pins used in the ma-chine, those needed in the field are discussed.

Caution:Do not touch the VRs or check pins not found in the lists. They are for use at the factory only,and require special tools and a level of accuracy based on correct measurement.

Caution:1. Some LEDs emit dim light because of leakage current when they are off; this is a normal

condition, and must be kept in mind.2. VRs that may be use in the field ...............................

Description

The re-circulating bar makes an idle swingwithout coming into contact with an originalimmediately after the re-circulating motor (M4)has turned on.

The sensor (S7) does not detect the leading edgeof an original 1500 msec at time of pickup.

When an original is placed, it rides over the paperstopper.

The number of originals placed on the originaltray after the removal of a jam changes asfollows; see Note 1:

The re-circulating lever fails to fall down to theoriginal tray, not enabling detection of the lastoriginal.

Reference:Normally, the original tray can accommodate50 sheets of A5, STMT, A4, B5, or LTR or25 sheets of A3, B4, 279x432 mm (11"x17"),or LGL.

The re-circulating lever falls to the original tray inthe middle of processing an original.

The original picked up is a non-default size.

[1] The original picked up is of a type not suitedto reduced page composition mode.

[2] The size of the original picked up is differentfrom that of the first original.

[No. 02, 03, 04]Use it to set conditions for the transmission of the RTN signal. If errors associated with thetransmission of the RTN signal tend to occur during reception, increase the parameter tomake the RTN signal transmission conditions less strict.

MemoThe error codes associated with the transmission of the RTN signal during reception are asfollows: ##104, ##107, ##114, ##201.RTN signal transmission condition (1) refers to the ratio of the number of error lines to thetotal number of lines per page of received images.RTN signal transmission condition (2) refers to the reference value** of a burst error *.RTN signal transmission condition (3) refers to the number of errors not reaching the refer-ence value for burst errors.

*Transmission errors continuing over multiple lines.**If ‘15’ is set, a transmission error covering continuous 15 lines will be identified as a burst error.

If any of these conditions is detected while image signals are received, the RTN signal will beissued after receiving the procedure signal of the transmitting device.

SELF DIAGNOSIS

Caution:1. If the self-diagnosis mechanism has turned on, the machine may be reset by turning the

power switch off and then on, with the exception of causes indicated by E000, E001,E002, or E003.The exceptions are made to prevent the user from resetting the machine as when the causeis an open circuit in the thermistor, which otherwise would overheat the fixing roller,causing the toner in the hopper to overflow.If the error is identified by E000 through E003, the machine will automatically turn itselfoff in about 20 sec if the power switch is turned on.If E000, E001, E002, or E003, the data in the RAM of the system controller PCB must becleared:

Resetting the Machine1) Execute the following in service mode: COPIER>FUNCTION>CLEAR>ERR.2) Press the Reset key twice to return to the Copy Mode screen.3) Turn off and then on the main power switch.

2. In the case of E202, a check may be made in service mode: COPIER>DISPLAY>ERR.

3. In the case of E677,• If it is indicated when the main power is on,

Suspect a fault in the hardware.Turning off and then on the power switch too fast at times causes E677, because ofa discrepancy in the initialization of the machine and the printer board. Be sure towait 5 sec or more before turning on the switch once you have turned it off.

• If it is indicated while the machine is being used normally,If the fault occurred during printing operation and, in addition, if the machine startsup normally when the print job has once been cancelled and the power switch isturned off and then on, suspect an excess load on the CPU.E677 can sometimes be indicated if an excess load is continuously imposed on theCPU of the printer board as by when processing a large amount of data while receiv-ing a large amount of data from the network.If this is the case, advise the user to cancel all print jobs, turn off and then on themain power switch, and send out the print jobs one by one.
