Causes
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Check visually and replace the paper conveying motor if neces-
sary.
Run maintenance item U030 and check if the paper conveying
motor operates when CN15-B3 on the engine PCB goes low. If
not, replace the paper conveying motor.
Run maintenance item U030 and check if CN15-B3 on the en-
gine PCB goes low. If not, replace the engine PCB.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Check visually and replace the deck drive motor if necessary.
Run maintenance item U030 and check if the deck drive motor
operates when CN16-6 on the engine PCB goes low. If not, re-
place the deck drive motor.
Run maintenance item U030 and check if CN16-6 on the engine
PCB goes low. If not, replace the engine PCB.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U073 and check if the scanner motor op-
erates when the motor drive coil energization pulse signals are
output at CN2-1, CN2-3, CN2-4 and CN2-6 on the scanner drive
PCB. If not, replace the scanner motor.
Run maintenance item U073 and check if the scanner motor op-
erates when CN1-10, CN1-11 and CN1-12 go low. If not, replace
the scanner drive PCB.
Check for continuity across the coil. If none, replace the paper
conveying fan motor.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U037 and check if CN3-B4 on the engine
PCB goes low. If not, replace the engine PCB.
Check for continuity across the coil. If none, replace the image
formation fan motor.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U037 and check if CN14-12 on the en-
gine PCB goes low. If not, replace the engine PCB.
