• The toner supply is low. You may be able to
temporarily extend the toner cartridge life. See
page 8.2. If this does not improve print quality,
install a new toner cartridge.
• The paper may not meet paper specifications
(for example, the paper is too moist or too
rough). See page 4.3.
• If the entire page is light, the print resolution
setting is too light or toner save mode is on.
Adjust the print resolution and toner save
mode in the printer properties. See the
Software Section.
• A combination of faded or smeared defects
may indicate that the printer needs cleaning.
See page 8.1.

reprinting the job.
• The moisture content of the paper is uneven
or the paper has moist spots on its surface.

• The toner cartridge may be defective. See
"Vertical repetitive defects" on the next
column.
• If these steps do not correct the problems,
contact a service representative.
