0001 When the orientation of an original is detected,
the result of detection is not communicated by
the original orientation detection PCB until the
next original is read.
- Replace the original orientation PCB.
- Replace the reader controller PCB.
0002 The result of detection of the last original is not
communicated 5 sec after the end of reading
the last original.
- Replace the original orientation PCB.
- Replace the reader controller PCB.
E243 The communication between the control panel PCB and MCON is faulty.
0000 A communication fault exists between the
CPUs of the control panel PCB and the main
controller PCB.
- Replace the control panel PCB.
- Replace the main controller PCB.
E251 The rotation of the inverter cooling fan is faulty.
0000 The lock signal (FM9LCK) arrives for 5 sec or
more although the inverter cooling fan (FM9)
is being driven.
- Check if there is no foreign material in the rotation
assembly of the inverter cooling fan.
- Check if the connecter (J1110) of the reader control
PCB is mounted properly.
- Replace the inverter cooling fan.
- Replace the reader controller PCB.
E302 Shading error
0000 During shading operation, the reader controller
PCB fails to end shading processing.
- Check if the connecter (J1502, J1503) of the CCD PCB
is mounted properly.
- Check if the connecter (J1107, J1108) of the reader
control PCB is mounted properly.
- Replace the CCD PCB.
- Replace the reader controller PCB.
E315 There is an error in image data.
The reader controller PCB is faulty. The main controller PCB is faulty.
0000 During image rotation, the encoding/decoding
has a fault.
- Replace the reader controller PCB.
- Replace the main controller PCB.
0007 If JBIG encoding is not completed - Replace the main controller PCB.
000D If there is an unexpected interrupt from the
hardware when JBIG is decoded
- Replace the main controller PCB.
000E If JBIG decoding is not completed within a
specified time
- Replace the main controller PCB.
E320 There is a time out error in the image reading processing.
0000 While an image is being read, the image read
end notice does not arrive at the reader
controller PCB within 60 sec from the CCD/
AP PCB.
- Check if the connecter (J1502, J1503) of the CCD PCB
is mounted properly.
- Check if the connecter (J1107, J1108) of the reader
control PCB is mounted properly.
- Replace the CCD PCB.
- Replace the reader controller PCB.
E400 Communication error with the ADF
0000 While the ADF is in standby, the
communication between ADF and copier is
interrupted for 5 sec or more. Or, when the
ADF is in operation, the communication
between ADF and copier is disrupted for 0.5
sec or more.
- Check if the communication cable between the ADF
and copier is connected properly.
- Replace the ADF controller PCB.
E402 The rotation of the ADF belt motor is faulty.
0000 The clock signal does not occur for 100 msec
when the belt motor drive signal is generated.
- Check if the cable between the ADF belt motor drive
PCB and ADF controller PCB is connected properly.
- Replace the ADF belt motor clock sensor.
- Replace the ADF belt motor.
- Replace the ADF belt motor drive PCB.
- Replace the ADF controller PCB.
E404 The rotation of the ADF delivery motor is faulty.
0000 The clock signal does not occur for 200 msec
when the delivery motor drive signal is
generated.
- Replace the ADF delivery motor.
- Replace the ADF delivery motor clock sensor.
- Replace the ADF controller PCB.
E405 The rotation of the ADF separation motor is faulty.
0000 The clock signal does not occur for 200 msec
when the separation motor drive signal is
generated.
- Replace the ADF separation motor.
- Replace the ADF separation motor clock sensor.
- Replace the ADF controller PCB.
E410 The rotation of the ADF pickup motor is faulty.
0000 The pickup roller height sensor 1 (PI8) or 2
(PI9) does not generate a signal within 2 sec
after the pickup motor is driven. Or, the pickup
roller home position sensor (PI7) does not
generate a signal within 2 sec after the pickup
motor is driven.
- Replace the ADF pickup motor.
- Replace the ADF pickup roller height sensor 1.
- Replace the ADF pickup roller height sensor 2.
- Replace the ADF pickup roller home position sensor.
- Replace the ADF controller PCB.
E412 The rotation of the ADF cooling fan is faulty.
0000 The lock signal arrives for 100 msec or more
although the cooling fan is being driven.
- Replace the ADF cooling fan.
- Replace the ADF controller PCB.
