Upper lift motor problem
• When the upper drawer is inserted,
the upper lift limit switch does not turn
on within 6 s of the upper lift motor
turning on and the upper lift limit
switch does not turn on in a retry
operation after turning off the upper
lift motor for 200 ms. At this time,
removal and insertion of the drawer is
prompted. Even after removal and
insertion of the drawer, the upper lift
limit switch does not turn on. This
problem occurs four times
continuously.
• During copying, the upper lift limit
switch does not turn on within 200 ms
of the upper lift motor turning on. At
this time, removal and insertion of the
drawer is prompted. Even after
removal and insertion of the drawer,
the upper lift limit switch does not turn
on. This problem occurs four times
continuously.
Lower lift motor problem
• When the lower drawer is inserted,
the lower lift limit switch does not turn
on within 6 s of the lower lift motor
turning on and the lower lift limit
switch does not turn on in a retry
operation after turning off the lower lift
motor for 200 ms. At this time,
removal and insertion of the drawer is
prompted. Even after removal and
insertion of the drawer, the lower lift
limit switch does not turn on. This
problem occurs four times
continuously.
• During copying, the lower lift limit
switch does not turn on within 200 ms
of the lower lift motor turning on. At
this time, removal and insertion of the
drawer is prompted. Even after
removal and insertion of the drawer,
the lower lift limit switch does not turn
on. This problem occurs four times
continuously.
Broken gears or
couplings of the

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 YC13-B9 on the main PCB goes
low when the upper lift limit switch is turned
off. If not, replace the upper lift limit switch.
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 YC13-B15 on the main PCB goes
low when the lower lift limit switch is turned
off. If not, replace the lower lift limit switch.
Reinsert the connector. Also check for con-
tinuity within the connector cable. If none,
