Printing quality problems

If the inside of the printer 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 SUGGESTED SOLUTIONS
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 toner cartridge
life. See "Replacing the toner cartridge" on
page 59. If this does not improve the print
quality, install a new toner cartridge.
• The paper may not meet paper
specifications; for example, the paper is too
moist or too rough. See "Selecting print
media" on page 24.
• If the entire page is light, the print
resolution setting is too low. Adjust the print
resolution. See the help screen of the
printer driver.
• A combination of faded or smeared defects
may indicate that the toner cartridge needs
cleaning.
• The surface of the LSU part inside the
printer may be dirty. See "Cleaning the
inside" on page 56.
SUGGESTED SOLUTIONS
Printing the PDF file as an
image may solve this
problem. Turn on Print As
Image from the Acrobat
printing options.
It will take longer to
print when you print a
PDF file as an image.
Reduce the photo size. If you
increase the photo size in the
software application, the
resolution will be reduced.
Suggested solutions: Change
the font setting (see
"Changing the font
setting" on page 22).
This is not a problem. Just
keep printing.
Set the correct paper size in
the Custom in the Paper tab
in the printer propeties. See
Software section.
