Developing fan motor
1 or 2 does not oper-
ate.
1. Broken developing fan
motor 1 or 2 coil.
Check for continuity across the coil. If none, replace developing
fan motor 1 or 2.
2. Poor contact in develop-
ing fan motor 1 or 2 con-
nector terminals.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
3. Defective developing fan
motor 1.
Run maintenance item U037 and check if developing fan motor 1
operates when YC2-9 on the fan motors drive PWB outputs 24 V.
If not, replace developing fan motor 1.
4. Defective developing fan
motor 2.
Run maintenance item U037 and check if developing fan motor 2
operates when YC2-11 on the fan motors drive PWB outputs 24 V.
If not, replace developing fan motor 2.
5. Defective fan motors
drive PWB.
Run maintenance item U037 and check if YC2-9 or YC2-11 on the
fan motors drive PWB outputs 24 V. If not, replace the fan motors
drive PWB.
6. Defective engine PWB. Run maintenance item U037 and check if YC13-3 on the engine
PWB outputs 24 V. If not, replace the engine PWB.

The image formation
fan motor does not
operate.
1. Broken image formation
fan motor coil.
Check for continuity across the coil. If none, replace the image for-
mation fan motor.
2. Poor contact in image
formation fan motor con-
nector terminals.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
3. Defective image forma-
tion fan motor.
Run maintenance item U037 and check if the image formation fan
motor operates when YC5-1 on the engine PWB outputs 24 V. If
not, replace the image formation fan motor.
4. Defective engine PWB. Run maintenance item U037 and check if YC5-1 on the engine
PWB outputs 24 V. If not, replace the engine PWB.

The developing duct
fan motor does not
operate.
1. Broken developing duct
fan motor coil.
Check for continuity across the coil. If none, replace the develop-
ing duct fan motor.
2. Poor contact in develop-
ing duct fan motor con-
nector terminals.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
3. Defective developing
duct fan motor.
Run maintenance item U037 and check if the developing duct fan
motor operates when YC5-2 on the engine PWB outputs 24 V. If
not, replace the developing duct fan motor.
4. Defective engine PWB. Run maintenance item U037 and check if YC5-2 on the engine
PWB outputs 24 V. If not, replace the engine PWB.
