Epson AcuLaser C9300 - Manual (Page 160)

The color looks different from what you see on the computer screen
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 can improve color matching between
different devices. For details, see the printer driver’s online help.
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.
Print Quality Problems
The background is dark or dirty
Cause What to do
You may not be using the correct type of paper for your
printer. If the surface of your paper is too rough, printed characters may
appear distorted or broken. Smooth, high-quality copier paper is
recommended for best results. See “Available paper types” on
page 191 for information on choosing paper.
The paper path inside the printer may be dusty. Clean internal printer components by printing three pages with
only one character per page.
