Trouble Shooting Information for C7000VP series
1.25 E822-0903
Description
There are some reported instances from the field where the error code ‘E822-0903’ was
indicated because a communication error occurred between the fixing duplex feed PCB and the
DC controller PCB 1-2 on the main station due to poor contact of the fixing duplexing drawer.
- E822-0903 can be displayed when the tandem guide lower cooling fan (FM358) causes an
error (sub station).
Field Remedy
1. Service mode > COPIER > Function > PART-CHK > FAN > enter '84' using the numeric
keys > OK > FAN-ON > check the operation of the fan. If the fan has no problem, it will
rotate for 10 sec at full speed.
2. If the fan does not rotate, re-fit the connector of the fan (FM358) to correct such a problem
as poor contact.
3. If the symptom still occurs, re-fit the fixing duplexing drawer connectors (fitted on the front
and back sides).
4. If the symptom still occurs, re-fit J4106 and J4070 connectors of the fixing duplex feed PCB,
and J1072 connector of the DC controller PCB 1-2.
5. If the symptom still occurs, replace the fan (FM358), the fixing duplex feed PCB, the DC
controller PCB 1-2 with new ones in this order.
