The machine does not
start up when the main
power switch is turned
on. Is no power supplied from the
electrical outlet? Correctly insert the power supply
plug into the electrical outlet.
Correctly insert the pow-
er supply plug into the
electrical outlet. Is the right-side door of the
machine open? Securely close the right-side door of
the machine.
Is there no paper that match-
es the document? Load paper of the appropriate size
into the paper tray.
The printed output is too
light. Was the print density
changed from the printer
driver? Check the printer driver setting.
Is the paper damp? Replace the paper with new paper.
(See p. 5-10, p. 5-14, p. 5-16 and
p. 5-18.)
The printed output is too
dark. Was the print density
changed from the printer
driver? Check the printer driver setting.
The printed output is
blurry. Is the paper damp? Replace the paper with new paper.
(See p. 5-10, p. 5-14, p. 5-16 and
p. 5-18.)
There are dark specks or
spots throughout the
printed output.
There are streaks in the
printed output. Is the electrostatic charger
dirty? Use the charger-cleaning tool to
clean the electrostatic charger. (See
p. 7-4.)
The image is not aligned
properly on the paper. Are the lateral guides incor-
rectly positioned against the
edges of the paper? Slide the lateral guides against the
edges of the paper.
Was curled paper loaded into
the paper tray? Flatten the paper before loading it.
The printed page is
curled. Was paper that curls easily
(as with recycled paper)
used? Remove the paper from the paper
tray, turn it over, and then load it
again.
Replace the paper with paper that is
not damp.
Even though the paper
misfeed was cleared,
prints cannot be pro-
duced. Are there paper misfeeds at
other locations? Check the control panel for other
paper misfeed indications, and then
remove any misfed paper at all other
locations. (See “Paper misfeed indi-
cations” on page 8-6.)
