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.
