Hard disk drive problem
• The hard disk drive cannot be ac-
cessed.
Upper lift motor problem [Drawer 1]
• When the drawer 1 is inserted, the lift
limit switch 1 does not turn on within
5.5 s of the upper lift motor turning
on.
• During copying, the lift limit switch 1
does not turn on within 200 ms of the
upper lift motor turning on.
Lower lift motor problem [Drawer 2]
• When the drawer 2 is inserted, the lift
limit switch 2 does not turn on within
5.5 s of the lower lift motor turning on.
• During copying, the lift limit switch 2
does not turn on within 200 ms of the
lower lift motor turning on.
Poor contact of
the hard disk drive
connector termi-
nals.
Defective hard
disk drive.
Defective main
PCB.
Broken gears or
couplings of the
upper lift motor.
Defective upper
lift motor.
Poor contact of
the lift motor 1
connector termi-
nals.
Defective lift limit
switch 1.
Poor contact of
the lift limit switch
1 connector termi-
nals.
Broken gears or
couplings of the
lower lift motor.
Defective lower lift
motor.
Poor contact of
the lower lift motor
connector termi-
nals.
Defective lift limit
switch 2.
Poor contact of
the lift limit switch
2 connector termi-
nals.
Check the connection of connectors CN2
on the main PCB and hard disk drive, and
the continuity across the connector termi-
nals. Repair or replace if necessary.
Run U906 (Resetting partial operation con-
trol) to cancel partial operation control. Run
U024 (HDD formatting) without turning the
power off to initialize the hard disk.
Replace the hard disk drive and check for
correct operation if the problem is still de-
tected after initialization.
Replace the main PCB and check for cor-
rect operation.
Replace the upper lift motor.
Check for continuity across the coil. If
none, replace the upper lift motor.
Reinsert the connector. Also check for con-
tinuity within the connector cable. If none,
repair or replace the cable.
Check if CN 7-6 on the engine PCB goes
low when the lift limit switch 1 is turned off.
If not, replace the lift limit switch 1.
Reinsert the connector. Also check for con-
tinuity within the connector cable. If none,
repair or replace the cable.
Replace the lower lift motor.
Check for continuity across the coil. If
none, replace the lower lift motor.
Reinsert the connector. Also check for con-
tinuity within the connector cable. If none,
repair or replace the cable.
Check if CN7-22 on the engine PCB goes
low when the lift limit switch 2 is turned off.
If not, replace the lift limit switch 2.
Reinsert the connector. Also check for con-
tinuity within the connector cable. If none,
repair or replace the cable.
