Care and Maintenance
One or more dark
vertical lines appear on
the print in all colors.
The color imaging unit
is scratched.
Replace the color
imaging unit; make
sure that the old color
imaging unit is not
exposed to light for
more than 45
seconds. If a new
color imaging unit
does not correct the
problem:
• Put the old color
imaging unit back
into the printer.
• Repack the new
color imaging unit.
The fuser is
damaged.
Replace the fuser.
A piece of the printed
image is missing and
reappears out of place,
approximately 129 mm
(5'') down the page.
The fuser’s internal
roller is not being
consistently oiled or
the fuser’s internal
roller is contaminated
with toner particles.
Print 5-10 pages of
blank pages to clean
the roller. If you still
see the problem:
• Replace the oil
supply roll.
If you still see the
problem:
• Replace the fuser.
The surface of the
printed image appears
to have vertical
scratches (visible by
holding the print at an
angle and observing the
“shine” of the image). At
first, the scratches
appear only on the
printed image;
eventually, dark vertical
scratches appear on
the imprinted portion of
the page.
The fuser is near its
useful life.
Replace the fuser
(depending on your
quality needs, you
can continue to print
until the dark vertical
lines appear).
Media frequently wraps
around the fuser.
The oil supply roll has
reached its useful life.
Replace the oil supply
roll.
