Printing quality problems
If the inside of the printer is dirty or paper has been loaded improperly, you 
may notice a reduction in print qualit y. See the table below to clear the 
problem.
The printer 
selects print 
materials from 
the wrong paper 
source The paper source 
selection in the 
printer properties 
may be incorrect.
For many software 
applications, the paper 
source selection is found 
under the 
Thin Paper  tab 
within the printer properties. 
Select the correct paper 
source. See the printer driver 
help screen.
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 of the page 
is blankThe 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 printer 
prints, but the 
text is wrong, 
garbled, or 
incompleteThe 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 
printer 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 printer 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 printer off 
and then back on again.

The toner cartridge 
is defective or out of 
toner. Redistribute the toner, if 
necessary. 
See Redistributing toner on

• The toner supply is low. You may be able 
to temporarily extend the toner cartridge 
life. See Replacing the toner cartridge on

quality, install a new toner cartridge.
• The paper may not meet paper  specifications; for example, the paper is too 
moist or too rough. See Selecting print 
media on page 24.
• If the entire page is light, the print 
resolution setting is too low. Adjust the print 
resolution. See the help screen of the

DropoutsIf faded areas, generally rounded, occur 
randomly on the page:
• A single sheet of paper may be defective. Try reprinting the job.
• The moisture content of the paper is  uneven or the paper has moist spots on its 
surface. Try a different brand of paper. 
See Selecting print media on page 24.
• The paper lot is bad. The manufacturing 
processes can cause some areas to reject

paper.
• Change the printer option and try again. Go  to printer properties, click  Paper tab, and 
set type to  Thick Paper . Refer to the 
Software section  for details.
If these steps do not correct the problem, 
contact a service representative.
White Spots  White spots appear on the page:
• The paper is too rough and a lot of dirt from 
the paper falls to the inner devices within 
the printer, which means the transfer belt 
may be dirty. Clean the inside of your 
printer. Contact a service representative.
• The paper path may need cleaning.  Contact a service representative.
Vertical linesIf black vertical streaks appear on the page:
• The drum inside the toner cartridge has probably been scratched. Remove the 
toner cartridge and install a new one. 
See Replacing the toner cartridge on

unacceptable:
• Change to a lighter weight paper. See Selecting print media on page 24.
• Check the printer’s environment: very dry  (low humidity) or high humidity (higher than

amount of background shading.
• Remove the old toner cartridge and install  a new one. See Replacing the toner 
cartridge on page 53.

cartridge. After the printout, if you still have 
the same problems, remove the toner 
cartridge and install a new one. 
See Replacing the toner cartridge on

• Parts of the printer may have toner on  them. If the defects occur on the back of 
the page, the problem will likely correct 
itself after a few more pages.
• The fusing assembly may be damaged. 
Contact a service representative.
Background scatterBackground scatter results from bits of toner 
randomly distributed on the printed page. 
• The paper may be too damp. Try printing with a different batch of paper. Do not open 
packages of paper until necessary so that 
the paper does not absorb too much 
moisture.
• If background scatter occurs on an  envelope, change the printing layout to 
avoid printing over areas that have 
overlapping seams on the reverse side. 
Printing on seams can cause problems.
• If background scatter  covers the entire 
surface area of a pr inted page, adjust the 
print resolution through your software 
application or the printer properties.
Misformed 
characters• If characters are improperly formed and 
producing hollow images, the paper stock 
may be too slick. Try a different paper. 
See Selecting print media on page 24.
• If characters are improperly formed and  producing a wavy effect, the scanner unit 
may need service. For service, contact a 
service representative.
Page skew• Ensure that the paper is loaded properly.
• Check the paper type and quality. See Selecting print media on page 24.

The scanner does 
not work • Ensure that you place the original to be 
scanned face down on the scanner glass, or 
face up in the ADF.

the Prescan function to se e if that works. Try 
lowering the scan resolution rate.

because of the large amount of memory 
required to analyze and reproduce the 
scanned image. Set your computer to the 
ECP printer mode through BIOS setting. It 
will help to increase the speed. For details 
about how to set BIOS, refer to your 
computer user’s guide.
