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, as many
variables as possible must be eliminated. The first step is to generate prints
using information pages embedded in the printer on laser paper from the
approved media list. The paper should be from a freshly opened ream that
has been acclimated to room temperature.
Go to the “Supplies” page at www.xerox.com or print the printer’s Paper Tips
page for supported paper and specialty media that has been tested and
approved for use in the Phaser 4500/4510 printer. If the print-quality defect is
still present when printing on approved media from a freshly opened ream of
paper, then media, software applications, and environmental conditions need
to be researched.
Determine the temperature and humidity under which the printer has been
operating. Compare this to the environmental specifications for the printer
found in “Environmental Specifications” on page 1-13 of this manual.
Temperature and humidity extremes can adversely affect the Xerographic and
fusing characteristics of the printer.
When analyzing a print-quality defect, first determine if the defect is repeating
or random. Continuous defects in the process direction, such as voids and
lines, are the most difficult to diagnose. The visible surfaces of all rollers
should be inspected for obvious defects.
