black dots occur, this is
because the print cartridge
rollers are contaminated with
foreign substance or paper
particles.
(1)38mm interval: Charged
roller
(2)95mm interval: OPC cycle
2. If white spots occur in a
black image at intervals of
95mm, or black spots occur
elsewhere, the OPC drum is
damaged or foreign sub-
stance is stuck to the surface.
3. If a black and white or
graphic image is partially bro-
ken at irregular intervals, the
transfer roller's life has been
expired or the transfer voltage
is abnormal.
