2nd transfer
roller 20 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. Replace the 2nd transfer
roller. This problem
may occur on
thick paper or
the image on
the back side of
the paper in
duplex printing.
