Xerox Phaser 3300MFP User Manual page 90

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.
Condition
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 13.4. 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 5.8.
• 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 page 2.4, respectively.
• A combination of faded or smeared defects
may indicate that the print cartridge needs
cleaning. See page 13.5.
• The surface of the LSU part inside the
machine may be dirty. Clean the LSU. See
page 13.2.
Toner specks • The paper may not meet specifications; for
example, the paper is too moist or too rough.
AaBbCc
See page 5.8.
• The transfer roller may be dirty. Clean the
AaBbCc
inside of your machine. See page 13.2.
AaBbCc
• The paper path may need cleaning. See page
AaBbCc
13.2.
AaBbCc
Dropouts If faded areas, generally rounded, occur
randomly on the page:
AaBbCc
• A single sheet of paper may be defective. Try
reprinting the job.
AaBbCc
• The moisture content of the paper is uneven
AaBbCc
or the paper has moist spots on its surface.
AaBbCc
Try a different brand of paper. See page 5.8.
AaBbCc • 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.
Suggested solutions
Condition
Vertical lines If black vertical streaks appear on the page:
• The drum inside the print cartridge has
probably been scratched. Remove the print
cartridge and install a new one. See
page 13.4.
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 13.2.
Gray background If the amount of background shading becomes
unacceptable:
• Change to a lighter weight paper. See
page 5.8.
• 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 print cartridge and install a
new one. See page 13.4.
Toner smear • Clean the inside of the machine. See
page 13.2.
• Check the paper type and quality. See
page 5.8.
• Remove the print cartridge and install a new
one. See page 13.4.
Vertical repetitive If marks repeatedly appear on the printed side of
defects the page at even intervals:
• The print cartridge may be damaged. If a
A a B b C c
repetitive mark occurs on the page, print a
A a B b C c
cleaning sheet several times to clean the
cartridge; see page 13.5. After the printout, if
A a B b C c
you still have the same problems, remove the
A a B b C c
print cartridge and install a new one. See page
A a B b C c
13.4.
• 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.
