Print-Quality Troubleshooting
Print-Quality Troubleshooting Overview
Print-quality defects can be attributed to printer components, consumables,
media, internal software, external software applications, and environmental
conditions. To successfully troubleshoot print-quality problems, eliminate as
many variables as possible. The first step is to generate prints using
information pages embedded in the printer on laser paper from the approved
media list. Refer to “Media and Tray Specifications” on page 1-18 for
supported and specialty media that have been tested and approved for use in
the WorkCentre 3210/3220. Use paper from a fresh ream that is acclimated to
room temperature and humidity.
If the print-quality defect is still present when printing on approved media from
an unopened ream of paper, then investigate software applications and
environmental conditions.
Check the temperature and humidity under which the printer is operating.
Compare this to the “Environmental Specifications” on page 1-12. Extreme
temperature and humidity can adversely affect the xerographic and fusing
characteristics of the printer.
When analyzing a print-quality defect, determine if the defect is repeating or
random occurrence. Continuous defects in the process direction, such as
Voids and Lines, are the most difficult to diagnose. Inspect the visible surfaces
of all Rollers for obvious defect. If no defects are found, replace the Print
Cartridge, Transfer Roller, Fuser, and Laser Unit one at a time until the defect
is eliminated.
