Troubleshooting
Printing quality problems
If the inside of the machine is dirty or paper has been loaded improperly,
you may notice a reduction in print quality. See the table below to clear the
problem.
A print job is
extremely
slow.
The job may be very
complex.
Reduce the complexity of the
page or try adjusting the print
quality settings.
Half the page
is blank.
The page orientation
setting may be
incorrect.
Change the page orientation in
your application. See the printer
driver help screen.
The paper size and
the paper size
settings do not
match.
Ensure that the paper size in the
printer driver settings matches the
paper in the tray.
Or, ensure that the paper size in
the printer driver settings matches
the paper selection in the
software application settings you
use.
The machine
prints, but
the text is
wrong,
garbled, or
incomplete.
The printer cable is
loose or defective.
Disconnect the printer cable and
reconnect. Try a print job that you
have already printed successfully.
If possible, attach the cable and
the machine to another computer
and try a print job that you know
works. Finally, try a new printer
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 then back on again.
Pages print,
but are blank.
The print cartridge is
defective or out of
toner.
Redistribute the toner, if
necessary. See page 64.
If necessary, replace the print
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 printer
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 solve this problem. 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.
CONDITION
POSSIBLE
CAUSE
SUGGESTED SOLUTIONS
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.
The machine
prints, but
the text is
wrong,
garbled, or
incomplete.
If you are under the
DOS environment,
the font setting for
your machine may
be set incorrectly.
Suggested solutions: Change the
font setting. See "Changing the
font setting" on page 31.
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
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 print cartridge life. See
page 65. If this does not improve the print
quality, install a new print cartridge.
•
The paper may not meet paper specifications;
for example, the paper is too moist or too
rough. See page 33.
•
If the entire page is light, the print resolution
setting is too low. Adjust the print resolution.
See the help screen of the printer driver.
•
A combination of faded or smeared defects
may indicate that the print cartridge needs
cleaning.
•
The surface of the LSU part inside the machine
may be dirty. Clean the LSU, contact a service
representative.
Toner specks
•
The paper may not meet specifications; for
example, the paper is too moist or too rough.
See page 33.
•
The paper path may need cleaning. See
"Cleaning the inside" on page 62.
