The Color Looks Different From What You See On The Computer Screen; Print Quality Problems; Dots Appear Every 30 Mm On The Printout - Epson AcuLaser C4200DN User Manual

The color looks different from what you see on
the computer 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.
PhotoEnhance may be selected in
the printer driver.

Print Quality Problems

Dots appear every 30 mm on the printout

Cause
The photoconductor unit needs to
be cleaned.
What to do
Although it is difficult to match colors
perfectly, selecting the printer driver's
ICM setting (for Windows XP, Me, 98, 2000,
or Server 2003) or ColorSync setting (for
Macintosh) can improve color matching
between different devices. For details,
see "Using the predefined settings" on
page 64 for Windows, and "Using the
predefined settings" on page 148 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 PhotoEnhance feature corrects the
contrast and brightness of the original
image data, and so may not be suitable
for printing vivid images.
What to do
Clean the photoconductor unit. See
"Cleaning the photoconductor unit" on
page 347 for details.
