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.
If you are in a
DOS
environment, the
font setting for
your machine
may be set
incorrectly.
See "Changing font setting" on
page 47
.
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
c
artridge.
The file may have
blan
k pages.
Check the file to ensure that it
does not contain blank pages.
Some parts, such
a
s the controller
or the board, may
be defective.
Contact a service representative.
The machine
does not print
PDF files
correctly. Some
graphics, text,
or illustrations
are missing.
Incompatibility
b
etween 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.
The machine
does not print
special- sized
paper, such as
billing paper.
Paper size and
pape
r size setting
do not match.
Set the correct paper size in the
Edit... in the Paper tab in the
Printing Preferences (See
"Opening printing preferences" on
page 55
).

SUGGESTED SOLUTIONS
CONDITION SUGGESTED SOLUTIONS
Light or faded print • 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 77). If this does not
improve the print quality, install a new toner
cartridge.
• Th
e paper may not meet paper specification; for
example, the paper may be too moist or rough
(See "Print media specifications" on page 93).
• If th
e 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 74).
Toner specks
• The paper may not meet specification; for
example, the paper may be too moist or rough
(See "Print media specifications" on page 93).
• Th
e 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 (See "Clearing paper jams"
on page 78).
Dropouts
If faded areas, generally rounded, occur randomly on
the page:
• A singl
e sheet of paper may be defective. Try
reprinting the job.
• T
he moisture content of the paper is uneven or
the paper has moist spots on its surface. Try a
different brand of paper (See "Print media
specifications" on page 93).
• T
he paper lot is bad. The manufacturing
processes can cause some areas to reject toner.
Try a different kind or brand of paper.
• Ch
ange the printer option and try again. Go to
Printing Preferences, click Paper tab, and set
type to Thick (See "Opening printing
preferences" on page 55).
• If
these steps do not correct the problem, contact
a service representative.
