White Black spot • Light or dark black
dots on the image
occur periodically. •
White spots occur in
the image periodi-
cally.
1. If light or dark periodical
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.

Cleaning Mode Print 4-5 times
repeatedly to remove, refer to
GP 5
. Especially check foreign
substance on the OPC surface,
then remove them with a clean
gauze moistened with IPA (Iso-
propyl Alcohol) not to damage
OPC if necessary. Never use
usual alcohol.
2. In case of 2 If they are not
disappeared by running OPC
Cleaning Mode Print 4-5 times.:
at intervals of 38mm -Replace
the print cartridge.: at intervals
of 95mm - Remove foreign sub-
stance.: Broken image -Replace
the print cartridge according to
carelessness.
3. In case of 3 -Exchange the
transfer roller because the life of
the transfer roller in use has
been expired. (Check the trans-
fer voltage and readjust if differ-
ent.)

substance or toner are stuck
to the terminal (contact point)
of the print cartridge.
(2)Check whether the state of
the terminal assembly is nor-
mal.
1. In case of 1
(1)If there is an evidence of dis-
assembling the print cartridge.
(2)If materials other than normal
