Print Quality

Before you perform the following service checks, do the following:
•
Be sure the paper or transparencies are the recommended
finish and weight. If the paper weight is incorrect (too stiff), it
may not provide 100% adhesion to the transfer drum. The
trailing edge will not be attracted to the drum and will "flap" on
each revolution causing blurs and smears at the bottom of the
page. This may eventually transfer stray toner on to the back or
front of the paper.
•
Be sure the printer and supplies are used in the proper
environmental range.
•
If in doubt about a printer driver or other customer application,
use the test prints described in the diagnostic aids.
•
Use the following start of call test to determine where the
symptom exists.

Cartridge End-of-Life

When printing a large number of pages with a low percentage of
color coverage, it is possible for the cartridge to wear out before
using all the toner. Regardless of the amount of toner used, the
internal rollers must make the same number of revolutions.
Maximum cartridge life is approximately 5500 pages. Depending on
color usage, it is possible to exceed this limit and still have a large
quantity of toner remaining in the cartridge. This condition will lead
to streaking and background, which will be covered elsewhere in this
service check.
