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” for supported and specialty media that have been tested and
approved for use in this printer. Use paper from a fresh ream that is acclimated to room temperature
and humidity.
If the image 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”. Extreme
temperature and humidity can adversely affect image quality.
When analyzing a 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.
Repeating Defect Measurement
When horizontal streaks or spots appear in a constant cycle, the problem might be due to damaged
Fuser, Drum Cartridge, Registration Rollers, or Transfer Rollers. Measure the interval between defects
and use the following table to identify the affected Roller.
Component Name Defect Distance (in / mm)
Fuser Pinch Roller 1.73 / 44.0
Exit Roller 1.73 / 44.0
Heat Roller 3.25 / 82.6
Pressure Belt 3.72 / 94.5
Transfer Roller 2nd BTR 2.62 / 67.5
Drum Cartridge Drum 3.70 / 94.2
BCR 1.48 / 37.7
Cleaning Roller 1.23 / 31.4
Registration Roller Registration Roller 1.73 / 44.0
If envelopes are wrinkling, ensure that an "Envelope Fuser" is installed (see PL3.5.1).
If wrinkling continues, see Wrinkled Envelope Troubleshooting.
