Cause
Printing will be performed by
the printer's graphic processing
function.
The paper type settings are not
configured correctly.
The paper is loaded reverse
side up. Printing on non-print
surfaces reduces print quality
and can damage the printer's
internal components.
Use of non-recommended toner
can result in a loss of print
quality and other problems.
The moisture in paper
evaporates because of the heat
generated during printing and
forms dews on the surface of
paper. These dews cause faint
spots or smears of toner on
printed images.
If the printer driver is configured
to use the graphics command,
the graphics command from the
printer is used to print.
A non-Windows operating
system is being used.
Solution
PCL 6
On the printer driver's
[Detailed Settings] tab,
click [Print Quality] in
"Menu:", and then select
[Raster] in the "Vector/
Raster:" list.
Check that the paper loaded on
the paper tray or bypass tray
matches the paper type set on
the display panel. For details
about paper type settings, see
page 52 "Paper Settings".
Before printing on special
paper, check its surface
carefully. For details about
special paper, see page 34
"Paper Precautions".
Use genuine manufacturer
toner. Contact your service
representative.
When you print on one side of
paper continuously in a low-
temperature environment, such
as early in the morning or late at
night, wait for about 10 minutes
before starting duplex printing.
If you want to print accurately,
set the printer driver to print
without using the graphics
command. For details about
settings for printer driver, see the
printer driver Help.
Check that the application
supports the printer driver.
