ERROR CODE AND TROUBLESHOOTING
Check Item
Are there uneven pitches of
approx 2.0 mm or 0.79 mm,
1.25 mm?
Is there any dent, damage or
deformation on the gear of the

the first drawer transport
clutch (CLT1 or CLT2)?

Is there any dent, damage or
deformation on the developer
drive unit, developer sleeve
and drive gears of the mixer?
Are there uneven pitches of
approx. 75 mm?
Is there any deformation to the
2nd transfer roller?
Since the 2nd transfer roller is
always in contact with the
transfer belt, the roller may
creep if the power has not
been turned on and the
equipment left unused for a
long time (1 month or more),
causing an uneven pitch.
