The Color Looks Different From What You See On The Computer Screen; Print Quality Problems; The Background Is Dark Or Dirty; White Dots Appear In The Printout - Epson AcuLaser C9300N 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).
PhotoEnhance may be selected in the printer driver.

What to do
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.
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
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.
