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 267 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.
The Density setting may be too dark. In the printer driver, click Extended Settings on the Optional
Settings tab, and then lighten the Density setting.
If the Density setting in the Printing Menu is set to 5, change it
back to 3.
There may be a temporary problem with the toner or
developer. Try to perform Dev Refresh or Toner Refresh in the Printer
Adjust Menu
. Note that Toner Refresh consumes the toner.
See “Printer Adjust Menu” on page 163 for details.
