Troubleshooting 3-79
Print-Quality Problems
Print-quality defects can be attributed to printer components, consumables, media,
internal software, external software applications or environmental conditions. To
successfully troubleshoot print quality problems, as many variables as possible must
be eliminated before replacing printer parts.
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. Defects occurring in only one color
are usually attributable to the Imaging Units or Toner Cartridges.
BEFORE USING ANY TROUBLESHOOTING PROCEDURE FOR
PRINT-QUALITY PROBLEMS, PERFORM THE FOLLOWING
STEPS:
■
See "Media and Tray Specifications" on page 1-16 for media that has been
tested and approved for use in the Phaser 7300 printer. If the print-quality
defect is still present when printing on approved media from an unopened
ream of paper, software applications, environmental conditions, and printer
hardware need to be researched.
■
Ensure the front panel and driver settings match the media loaded in the tray.
■
Use service diagnostics to determine if the temperature and humidity meet the
environmental specifications, see "Environmental Specifications" on
page 1-15. Temperature and humidity extremes can adversely effect the
Xerographic and fusing characteristics of the printer.
■
Cycle power to the printer. This will initiate the Color Registration and
Automatic Density Control (ADC) Calibrations.
■
Use the printer’s internal test prints to verify the problem is with the printer
and not with the user settings or application.

To isolate repeating defect problems to a specific part, print the Repeating
Defects Page.
■
Clean and remove any debris or obstructions from the printers paper path.
■
Vacuum any obvious toner spills within the printer.
