Image Quality
Image Quality Overview
Image-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 1-29 for supported and specialty media
that have been tested and approved for use in the Phaser 3010/3040/WorkCentre
3045s. Use paper from a fresh ream that is acclimated to room temperature and
humidity.
If the print-quality defect remains after printing on approved media from an
unopened ream of paper, then investigate applications and environmental
conditions.
Determine the temperature and humidity under which the printer is operating.
Compare this to the “Environmental Specifications” on page 1-24. Extreme
temperature and humidity can adversely affect print quality.
When analyzing a print-quality defect, first determine if the defect is repeating or
a 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 defects.
Defects Associated with Specific Printer Components
Some print-quality problems are associated with specific assemblies. Refer to the
