Image-Quality Problems Overview - Xerox WorkCentre C2424DX Service Manual

Image-Quality Problems Overview

Image-quality defects can be attributed to the following:
system hardware components or communication
consumables
media
internal or external software applications
environmental conditions
To successfully troubleshoot print/copy-quality problems, as many variables as
possible must be eliminated.
Note
To aid in troubleshooting image-quality issues, generate prints using the
information pages embedded in the system software on paper from the approved
media list. (See the media specifications in the section "Tray and Media
Specifications" on page 1-16 for media that has been tested and approved for use
in this system.) The paper should be from an unopened ream that has been
acclimated to room temperature.
If the print-quality defect is still present when printing on approved media from an
unopened ream of paper other conditions need to be researched.
The following steps should be performed for diagnosing print-quality problems:
1. Verify the media being used and the environment for the system are within
specification.
2.
Isolate the print-quality defect to either a malfunction of the DADF/scanner (IIT)
or a malfunction of the print engine (IOT), and once identified:
Troubleshoot the DADF/Scanner
Troubleshoot the print engine
When analyzing a print-quality defect from a print engine malfunction,
determine if the defect occurs:
in all colors
in only one color
as a repeating or random defect
