Print Quality Problems; The Background Is Dark Or Dirty - Epson AcuLaser C1900 Reference Manual

screen
Cause
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).
For Macintosh, the System
Profile setting is not in use.
PhotoEnhance4 may be
selected in the printer driver.

Troubleshooting
What to do
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.
To apply ColorSync properly, your
input device and the application must
support ColorSync, and a System
Profile must be used for your monitor.
The PhotoEnhance4 feature corrects the
contrast and brightness of the original
image data for printing images more
vivid. Deselect the PhotoEhance4
feature if necessary.
What to do
Replace the photoconductor unit. See
"Photoconductor Unit" on page 246.
