10. Faulty stapler shift motor
11. Faulty swing motor (related to MS6)
Checks
Check the stapler shift home
position sensor. Is the sensor
normal?
Is the wiring between the
finisher controller PCB and
the stapler shift motor
normal?
Is there any mechanical
obstacle in the path of the
stapler shift base?
Replace the stapler motor. Is
the problem corrected?
Cause
Stapler shift home
position sensor (PI7)
Wiring
Stapler shift base
Stapler shift motor (M4)
