Print Quality Problems
The background is dark or dirty
Cause
What to do
Printed colors do not exactly
match the colors on your
monitor, since printers and
monitors use different color
systems: monitors use RGB
(red, green, and blue), while
printers typically use CMYK
(cyan, magenta, yellow, and
black).
Although it is difficult to match colors
perfectly, selecting the printer driver’s
ICM setting (for Windows Me, 98, 95,
XP, or 2000) or ColorSync setting (for
Macintosh) can improve color matching
between different devices. For details,
see “Using the predefined settings” on
page 51 for Windows, and “Using the
predefined settings” on page 111 for
Macintosh.
For Macintosh, the System
Profile setting is not in use.
To apply ColorSync properly, your
input device and the application must
support ColorSync, and a System
Profile must be used for your monitor.
PhotoEnhance4
may be
selected in the printer driver.
The PhotoEnhance4 feature corrects the
contrast and brightness of the original
image data for printing images more
vivid. Deselect the PhotoEhance4
feature if necessary.
Cause
What to do
There may be a problem with
the photoconductor unit.
Replace the photoconductor unit. See
“Photoconductor Unit” on page 246.
