Printing quality problems
If the inside of the machine is dirty or paper has been loaded improperly,
there might be a reduction in print quality. See the table below to clear the
problem.
Pages print, but
they are blank.
The toner
cartridge is
defective or out
of toner.
Redistribute the toner, if
necessary.
If necessary, replace the toner
cartridge.
The file may
have blank
pages.
Check the file to ensure that it
does not contain blank pages.
Some parts, such
as the controller
or the board,
may be
defective.
Contact a service representative.
The machine
does not print
PDF file
correctly. Some
parts of
graphics, text,
or illustrations
are missing.
Incompatibility
between the PDF
file and the
Acrobat
products.
Printing the PDF file as an image
may enable the file to print. 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.
The print
quality of
photos is not
good. Images
are not clear.
The resolution of
the photo is very
low.
Reduce the photo size. If you
increase the photo size in the
software application, the resolution
will be reduced.
Before printing,
the machine
emits vapor
near the output
tray.
Using damp
paper can cause
vapor during
printing.
This is not a problem. Just keep
printing.
The machine
does not print
special- sized
paper, such as
billing paper.
Paper size and
paper size
setting do not
match.
Set the correct paper size in the
Edit... in the Paper tab in the
Printing Preferences. (See
"Opening printing preferences" on
page 32.)

toner cartridge life. (See "Redistributing toner"

for example, the paper may be too moist or
rough. (See "Print media specifications" on

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.

may indicate that the toner cartridge needs
cleaning. (See "Cleaning the inside" on

machine may be dirty. (See "Cleaning the
