Print Quality Problems

Dots appear every 30 mm on the printout

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 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.

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.

PhotoEnhance may be selected in

the printer driver.

The PhotoEnhance feature corrects the

contrast and brightness of the original

image data, and so may not be suitable

for printing vivid images.

Cause What to do

The photoconductor unit needs to

be cleaned.

Clean the photoconductor unit. See

"Cleaning the photoconductor unit" on

page 347 for details.
