C1010 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 by turning off
the upper lift motor for 200 ms and
retrying twice.
• During copying, the upper lift limit
switch does not turn on within 200 ms
of the upper lift motor turning on.
C1020 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 by turning off
the lower lift motor for 200 ms and
retrying twice.
• During copying, the lower lift limit
switch does not turn on within 200 ms
of the lower lift motor turning on.
C1030 Desk upper lift motor problem
• When the upper drawer of the paper
feed desk* is inserted, the desk upper
lift limit switch does not turn on within
6 s of the desk upper lift motor turning
on and the desk upper lift limit switch
does not turn on by turning off the
desk upper lift motor for 200 ms and
retrying twice.
• During copying, the desk upper lift
