Causes
Run maintenance item U030 and check if YC16-B11, YC16-B12,
YC16-B13 and YC16-B14 on the main PCB go low. If not,
replace the main PCB.
Check for continuity across the coil. If none, replace the upper
lift motor.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Check if 24 V DC is output across YC13-A17 on the main PCB
right after the upper drawer is installed. If not, replace the main
PCB.
Check for continuity across the coil. If none, replace the lower lift
motor.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Check if 24 V DC is output across YC13-B7 on the main PCB
right after the lower drawer is installed. If not, replace the main
PCB.
Check for continuity across the coil. If none, replace the scanner
motor.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Check for continuity across the coil. If none, replace cooling fan
motor 1.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, repair or replace the cable.
Check for continuity across the coil. If none, replace cooling fan
motor 2.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, repair or replace the cable.
Check for continuity across the coil. If none, replace cooling fan
motor 3.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, repair or replace the cable.
