Troubleshooting
_ 84
White Spots
If white spots appear on the page:
•
The paper is too rough and a lot of dirt from a
paper falls to the inner devices within the
machine, so the transfer roller may be dirty.
Clean the inside of your machine (See "Cleaning
•
The paper path may need cleaning (See
"Cleaning the inside" on page 74).
Vertical lines
G
If black vertical streaks appear on the page:
•
The surface (drum part) of the toner cartridge
inside the machine has probably been scratched.
Remove the toner cartridge and install a new one
(See "Replacing the toner cartridge" on page 89).
If white vertical streaks appear on the page:
•
The surface of the LSU part inside the machine
may be dirty (See "Cleaning the inside" on
page 74).
Black background
If the amount of background shading becomes
unacceptable:
•
Change to a lighter weight paper (See "Print
media specifications" on page 93).
•
Check the environmental conditions: very dry
conditions or a high level of humidity (higher than
80% RH) can increase the amount of background
shading.
•
Remove the old toner cartridge and, install a new
one (See "Replacing the toner cartridge" on
page 89).
Toner smear
If toner smears on the page:
•
Clean the inside of the machine (See "Cleaning
•
Check the paper type and quality (See "Print
media specifications" on page 93).
•
Remove the toner cartridge and then, install a
new one (See "Replacing the toner cartridge" on
page 89).
Vertical repetitive
defects
If marks repeatedly appear on the printed side of the
page at even intervals:
•
The toner cartridge may be damaged. If you still
have the same problem, remove the toner
cartridge and, install a new one (See "Replacing
the toner cartridge" on page 89).
•
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
scatter
A
Background scatter results from bits of toner
randomly distributed on the printed page.
•
The paper may be too damp. Try printing with a
fresh ream 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 quality
through your software application or in
