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. 
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. 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 Specifications 
on print media on page 4.3.)
• 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 and refer to Software 
section, respectively.
• A combination of faded or smeared defects 
may indicate that the toner cartridge needs 
cleaning. Contact a service representative.
• The surface of the LSU part inside the 
machine may be dirty. Clean the LSU (see 
page 8.2).
Toner specks• The paper may not meet specifications; for 
example, the paper may be too moist or 
rough. (See Specifications on print 
media on page 4.3.)
• The paper path may need cleaning. Contact 
a service representative.
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 
Specifications on print media on page 4.3.)
• The paper lot is bad. The manufacturing 
processes can cause some areas to reject 
toner. Try a different kind or brand of paper.
• If these steps do not correct the problem, 
contact a service representative.
White Spots White spots appear on the page:
• The paper path may need cleaning. Contact 
a service representative.
Vertical linesIf black vertical streaks appear on the page:
• The toner cartridge has probably been 
scratched. Remove the toner cartridge and 
install a new one.
If white vertical streaks appear on the page:
• The surface of the LSU part inside the 
machine may be dirty. Clean the LSU (see 
page 8.2).
Color or Black 
backgroundIf the amount of background shading becomes 
unacceptable:
• Change to a lighter weight paper. (See 
Specifications on print media on page 4.3.)
• Check the environmental conditions: very 
dry conditions (low humidity) or a high level 
of humidity (higher than 80% RH) can 
increase the amount of background 
shading.
• Remove the old toner cartridge, and then 
install a new one. (See Replacing the toner 
cartridge on page 8.5.)
Toner smear• Clean the inside of the machine. Contact a 
service representative to clean the inside of 
the machine.

Vertical repetitive 
defectsIf marks repeatedly appear on the printed side 
of the page at even intervals:
• Clean the inside of the machine. Contact a 
service representative to clean the inside of 
the machine. After cleaning the inside of the 
machine, if you still have the same 
problems, install a new toner cartridge of the 
problem color. See Replacing the toner 
cartridge on page 8.5.
• 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 covers the entire 
surface area of a printed page, adjust the 
print resolution through your software 
application or in printer properties.
Misformed 
characters• If characters are improperly formed and 
producing hollow images, the paper stock 
may be too slick. Try different paper. (See 
Specifications on print media on page 4.3.)
• If characters are improperly formed and 
producing a wavy effect, the scanner unit 
may need service. Contact a service 
representative.
Page skew• Ensure that the paper is loaded properly.
