Troubleshooting_ 116
Printing quality problems
If the inside of the machine is dirty or paper has been loaded improperly,
there might be a reduction in print quality. See the table below to clear the
problem.
The machine
prints, but the
text is wrong,
garbled, or
incomplete.
The machine cable
is loose or
defective.
Disconnect the machine
cable and reconnect. Try a
print job that you have
already printed successfully.
If possible, attach the cable
and the machine to another
computer that you know
works and try a print job.
Finally, try a new machine
cable.
The wrong printer
driver was selected.
Check the application’s
printer selection menu to
ensure that your machine is
selected.
The software
application is
malfunctioning.
Try printing a job from
another application.
The operating
system is
malfunctioning.
Exit Windows and reboot the
computer. Turn the machine
off and back on again.
If you are in a DOS
environment, the
font setting for your
machine may be
set incorrectly.
Change the language
setting. (See "Changing the
font setting" on page 43.)
Pages print, but
they are blank.
The toner cartridge
is defective or out of
toner.
Redistribute the toner, if
necessary.
If necessary, replace the
toner cartridge.
The file may have
blank pages.
Check the file to ensure that
it does not contain blank
pages.
Some parts, such
as the controller or
the board, may be
defective.
Contact a service
representative.
The machine
does not print
PDF file correctly.
Some parts of
graphics, text, or
illustrations are
missing.
Incompatibility
between the PDF
file and the Acrobat
products.
Printing the PDF file as an
image may enable the file to
print. Turn on Print As
Image from the Acrobat
printing options.
It will take longer to
print when you print a
PDF file as an image.
The print quality
of photos is not
good. Images are
not clear.
The resolution of
the photo is very
low.
Reduce the photo size. If
you increase the photo size
in the software application,
the resolution will be
reduced.
Before printing,
the machine
emits vapor near
the output tray.
Using damp paper
can cause vapor
during printing.
This is not a problem. Just
keep printing.
CONDITION POSSIBLE
CAUSE
SUGGESTED
SOLUTIONS
The machine
does not print
special- sized
paper, such as
billing paper.
Paper size and
paper size setting
do not match.
Set the correct paper size in
the Custom in the Paper tab
in the Printing Preferences.
(See "Paper tab" on
page 55.)

•If a vertical white streak or faded area
appears on the page, the toner supply is low.
You may be able to temporarily extend the
toner cartridge life. (See"Redistributing toner"
on page 107.) If this does not improve the
print quality, install a new toner cartridge.
•The paper may not meet paper specifications;
for example, the paper may be too moist or
rough. (See "Print media specifications" on
page 131.)
•If the entire page is light, the print resolution
setting is too low or the toner save mode is
on. Adjust the print resolution and turn the
toner save mode off. See the help screen of
the printer driver.
•A combination of faded or smeared defects
may indicate that the toner cartridge needs
cleaning. (See "Cleaning the inside" on
page 105.)
•The surface of the LSU part inside the
machine may be dirty. (See "Cleaning the
inside" on page 105.)
Toner specks •The paper may not meet specifications; for
example, the paper may be too moist or
rough. (See "Print media specifications" on
page 131.)
•The transfer roller may be dirty. Clean the
inside of your machine. Contact a service
representative.
•The paper path may need cleaning. Contact a
service representative.
