0001 - Although the polygon motor has been turned on,

VLOCK is not detected at all within 76.5 sec.
- At time of a shift from full-speed to half-speed
control, VLOCK is not detected at all for 7.5 sec.
- At time of half-speed control, a check is made of
VLOCK at intervals of 100 msec. An error will be
identified if it is not detected 10 times
continuously.

- Replace the laser scanner unit.
- Replace the DC controller PCB.

E121

There is a controller cooling fan error.

0001 Even though the controller cooling fan has been

turned on, the controller cooling fan stop signal has
been detected for 5 sec or more.

- Check the connector for any fault in connection.
- Replace the fan.

E196

The EEPROM is faulty.

1abb There is a mismatch between the data that has been

written in EEPROM and the data that has been
read. (a: chip No. 0 through 5; bb: chip faulty
address)

- Initialize the RAM.
- Replace the EEPROM.
- Replace the DC controller PCB.

2abb The ID in EEPROM that has been read and the ID

in ROM are compared. An error will be identified
if they do not match. (a: chip No. 0 through 5; bb:
chip faulty address)

3abb When the main power is turned on, the ID in

EEPROM and the ID in ROM are compared. An
error will be identified if they do not match. (a: chip
No. 0 through 5; bb: chip faulty address)

- Check the position and condition of the
EEPROM.
- Initialize the RAM.
- Replace the EEPROM.
- Replace the DC controller PCB.

E202

There is a scanner HP error.

0001 An error has occurred when the sensor was moved

to home position.
The scanner HP sensor is faulty; the scanner motor
is faulty; the reader controller PCB is faulty.

- Check the connector for any fault in connection.
- Replace the scanner HP sensor.
- Replace the scanner motor.
- Replace the reader controller PCB.

0002 An error has occurred when the sensor was moved

from home position.
The scanner HP sensor is faulty; the scanner motor
is faulty; the reader controller PCB is faulty.

E225

The intensity of light is inadequate.

0001 At time of shading, the intensity if below a specific

level.

- Check the connector for any fault in connection.
- Replace the scanning lamp.
- Replace the inverter PCB.
- Replace the reader controller PCB.

0002 ADFThe intensity is below a specific level

between sheets (ADF).

E227

there is an error in the power supply (24 V).

0001 At power-on, the 24-V port is OFF.

- Check the connector for any fault in connection.
- Replace the power supply.

0002 At the start of a job, the 24-V port is OFF.
0003 At the end of a job, the 24-V port is off.
0004 When a load is driven, the 24-V port is OFF.

E240

The communication between the main controller PCB and the DC controller PCB is faulty.

0000 There is an error in the communication between the

main controller PCB and the CPU of the DC
controller PCB.

- Check the connector for any fault in connection.
- Replace the DC controller PCB.
- Replace the main controller PCB.

E248

There is an EEPROM error.

0001 An error has occurred at power-on.

- Replace the EEPROM.
- Replace the reader controller PCB.

0002 An error has occurred at time of write operation.
0003 An error has occurred at time of read operation

after write operation.

E315

There is a fault in the image data.

0007 There is a JIBIG encode error.

- Turn off and then back on the power.

000d There is a JBIG decode error.

E400

There is an ADF communication error.

0001 There is a check sum error.

- Check the connector for any fault in connection.
- Replace the reader controller PCB.
- Replace the ADF controller PCB.

0002 There is a reception status error.
0003 There is a reception interrupt error.

E413

There is a fault in the ADF shift motor.

0001 The output of the shift HP sensor is identified as

indicating open.

- Check the connector for any fault in connection.
- Replace the sensor and motor in question.
- Check the mounting condition of the area around
the cam.
