Your paper may be moist or damp. Printing is sensitive to moisture
absorbed by the paper. Do not store your paper in a humid or damp
environment.
If this does not solve the problem, install a new imaging cartridge as
described later in this chapter. Then print several pages to check the
print quality.
Toner smudges
Turn off the printer. Remove the imaging cartridge, shake it from side
to side to distribute the toner, and wipe the bottom of it with a clean,
dry cloth.
Clean the paper path inside the printer using a clean, soft, dry cloth.
Clean internal printer components by printing three pages with only
one character per page.
If the problem remains, replace the imaging cartridge as described
later in this chapter.
Missing areas on printed image
Your paper may be moist or damp. Printing is sensitive to moisture
absorbed by the paper. The higher the moisture content in the paper,
the lighter the printed output. Do not store your paper in a humid or
damp environment.
You may not be using the correct type of paper for your printer. If the
surface of your paper is too rough, printed characters appear distorted
or broken. Smooth, high-quality copier paper is recommended for best
results. See Chapter 1
for information on choosing paper.
