Note:
1. When the self diagnosis mechanism has detected an error, you may reset the
copier by turning off its switch once.
This, however, does not apply to 'E000','E001','E002','E003' and 'E800'. To reset
these error codes, select No.401 in service mode [4], and press the OK key. This
arrangement is adopted to prevent the user from casually resetting the copier
when the cause of the error is an open circuit in the thermistor, thereby protecting
the rollers inside the fixing assembly against heat damage.
2. If 'E000','E001','E002','E003', or 'E004' is detected, the copier forces off the
power switch in about 2 sec.

Cause
faulty)

Description
•The blank shutter home position signal
(BLHP) is not generated within 7 sec
after the power switch has been turned
on.
•The blank shutter home position signal
(BLHP) does not turn off within 1 sec
after it has been generated.
An error has occurred in the
communication between the
microprocessor master (IC116) and the
microprocessor slave (IC104).
IC117 on the DC controller PCB cannot
be initialized at time of power-on.
IC117 on the DC controller PCB has
gone out of order at time of power-on.
The communication IC on the DF
controller PCB has gone out of order.
The communication IC on the pedestal
controller PCB has gone out of order. A
communication error has occurred.
An open circuit in the auto power off
circuit has been detected.
