Developer unit
Check if offsets are observed at
an constant interval of 39 mm,
which is equivalent to the cir-
cumference of the developing
roller.
If offsets are observed at an constant interval
of 39 mm, which is equivalent to the
circumference of the developing roller, replace
the developer unit.
(Waste toner is not properly sweeped from the
