Suggested solutions
Reduce the photo size. If
you increase the photo size
in the software application,
the resolution will be
reduced.
This is not a problem. Just
keep printing.
Set the correct paper size in
the Paper tab in the
Printing Preferences (See
"Opening printing
preferences" on page 2).
Suggested Solutions
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
toner cartridge life (See"Redistributing toner"
on page 1). 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 "Print media specifications" on
page 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.
A combination of faded or smeared defects
may indicate that the toner cartridge needs
cleaning (See "Cleaning the inside" on
page 2).
The surface of the LSU part inside the
machine may be dirty (See "Cleaning the
inside" on page 2).
The paper may not meet specifications; for
example, the paper may be too moist or rough

Suggested Solutions
If 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 "Print
media specifications" on page 3).
• 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 Printing Preferences, click Paper tab,
and set type to Thick (See "Opening printing
preferences" on page 2).
• If these steps do not correct the problem,
contact a service representative.
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 inside" on page 2).
• The paper path may need cleaning (See
"Cleaning the inside" on page 2).
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 2).
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 2).
If vertical streaks appear on the page:
• The surface of the scanner glass and its
white sheet may be dirty. Clean these unit
(See "Cleaning the scan unit" on page 3).
If the amount of background shading becomes
unacceptable:
• Change to a lighter weight paper (See "Print
media specifications" on page 3).
• 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 2). If this problem
persists, contact a service representative.
