Control PWB EEPROM error

Detecting control PWB EEPROM (U300)

communication error.

Improper installa-

tion control PWB

EEPROM (U300).

Check the installation of the EEPROM

(U300) and remedy if necessary (See page

1-5-19).

Defective control

PWB.

Replace the control PWB (See page 1-5-

19).

0420

Paper feeder communication error

Communication error between control

PWB and optional paper feeder.

Improper installa-

tion paper feeder.

Follow installation instruction carefully again.

Defective harness

between control

PWB (YC318) and

paper feeder inter-

face connector, or

improper connec-

tor insertion.

Reinsert the connector. Also check for conti-

nuity within the connector harness. If none,

remedy or replace the harness.

Defective control

PWB.

Replace the control PWB (See page 1-5-

19).

Defective harness

between PF main

PWB (YC5) and

paper feeder inter-

face connector, or

improper connec-

tor insertion.

Reinsert the connector. Also check for conti-

nuity within the connector harness. If none,

remedy or replace the harness (Refer to the

service manual for the paper feeder).

Defective PF main-

PWB.

Replace the PF main PWB (Refer to the ser-

vice manual for the paper feeder).

2000

Main motor error

The main motor ready input is not given

for 2 s during the main motor is ON.

Defective harness

between main

motor (CN1) and

control PWB

(YC305), or

improper connec-

tor insertion.

Reinsert the connector. Also check for conti-

nuity within the connector harness. If none,

remedy or replace the harness.
