CONDITIONSUGGESTED SOLUTIONS
Light or faded printIf 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 page 41. If this does not improve 
the print quality, install a new toner 
cartridge.
• The paper may not meet paper 
specifications; for example, the paper is too 
moist or too rough. See page 31.
• 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 toner cartridge needs 
cleaning.
• The surface of the LSU part inside the 
machine may be dirty. Clean the LSU by 
opening and closing the front cover several 
times and if the problem still occurs call the

Toner specks• The paper may not meet specifications; for 
example, the paper is too moist or too 
rough. See page 31.
• The paper path may need cleaning. See 
Cleaning the inside on page 38.
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 
page 31.
• The paper lot is bad. The manufacturing 
processes can cause some areas to reject 
toner. Try a different kind or brand of 
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 machine, which means the transfer belt 
may be dirty. Clean the inside of your 
machine. Contact a service representative.
• The paper path may need cleaning. 
Contact a service representative.
Vertical linesIf black vertical streaks appear on the page:
• The imaging unit has probably been 
scratched. Remove the imaging unit and 
install a new one. See page 42.

Color or Black 
backgroundIf the amount of background shading becomes 
unacceptable:
• Change to a lighter weight paper. See 
page 31.
• Check the machine’s environment: very dry 
(low humidity) or high humidity (higher than 
80% RH) conditions can increase the 
amount of background shading.
• Remove the old toner cartridge and install 
a new one. See page 41.
Toner smear• Clean the inside of the machine. See page 
38.
• Check the paper type and quality. See page 
31.
• Remove the toner cartridge and install a 
new one. See page 41.
Vertical repetitive 
defectsIf marks repeatedly appear on the printed side 
of the page at even intervals:
• The toner cartridge may be damaged. If a 
repetitive mark occurs on the page, print a 
cleaning sheet several times to clean the 
cartridge. After the printout, if you still have 
the same problems, remove the toner 
cartridge and install a new one. See page 
41.
• Parts of the machine 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 printed page, adjust the 
print resolution through your software 
application or the printer properties.
