Print-Quality Troubleshooting
Print-Quality Problems 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 1-19 for
supported and specialty media that have been tested and approved for use in
the Phaser 6130 Color Laser Printer. 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.
Print the Configuration page to determine the temperature and humidity under
which the printer is operating. Compare this to the “Environmental
Specifications” on page 1-13. Extreme temperature and humidity can
adversely affect the xerographic and fusing characteristics of the printer.
When analyzing a print-quality defect, first determine if the defect occurs in all
colors or only one color and if it 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 Imaging Unit, Laser Unit, Transfer
Unit, and Fuser one at a time until the defect is eliminated.
Defects Associated with Specific Printer Components
Some print-quality problems can be associated with specific assemblies; the
most common problems and the associated assemblies are listed in this
section. Refer to the specific print-quality troubleshooting procedure for detail
information.
