Troubleshooting Image Quality
Basic Image Quality Troubleshooting
Image-quality defects can be attributed to printer components, consumables, media, internal software, external
software applications, and environmental conditions. To successfully troubleshoot image-quality problems,
eliminate as many variables as possible. The first step is to generate prints using printable pages embedded in the
printer on paper from the Supported Media List. Use paper from a fresh, unopened ream that is acclimated to
room temperature and humidity. If the print-quality defect is still present when printing on approved media, then
investigate software applications and environmental conditions.
The printer uses an Imaging Unit to develop a latent image to form the final image. In most cases, image-quality
defects are the result of one particular component in the print engine. When a single component of the Imaging
Unit is causing a print quality defect, replace the Imaging Unit.
When analyzing an image-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. Inspect the visible surfaces of
all rollers for obvious defects. If no defects are observed, replace the Imaging Unit, Transfer Unit, and Fuser one
at a time until the defect is eliminated.
