SUGGESTED SOLUTIONS
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 inside" on page 88).
The paper path may need cleaning (See
"Cleaning the inside" on page 88).
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 107).
The surface of the LSU part inside the
machine may be dirty (See "Cleaning the
inside" on page 88).
Change to a lighter weight paper (See "Print
media specifications" on page 111).
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 107).
Clean the inside of the machine (See
"Cleaning the inside" on page 88).
Check the paper type and quality (See "Print
media specifications" on page 111).
Remove the toner cartridge and then, install
a new one (See "Replacing the toner
cartridge" on page 107).
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 107).
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.

SUGGESTED SOLUTIONS
Background 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 in Printing Preferences (See
"Opening printing preferences" on page 53).
• If characters are improperly formed and
producing hollow images, the paper stock
may be too slick. Try different paper (See
"Print media specifications" on page 111).
• If characters are improperly formed and
producing a wavy effect, the scanner unit may
need service (See "Cleaning the scan unit" on
page 89).
• Ensure that the paper is loaded properly.
• Check the paper type and quality (See "Print
media specifications" on page 111).
• Ensure that the guides are not too tight or too
loose against the paper stack.
• Ensure that the paper is loaded properly.
• Check the paper type and quality. Both high
temperature and humidity can cause paper
curl (See "Print media specifications" on
page 111).
• Turn the stack of paper over in the tray. Also
try rotating the paper 180° in the tray.
