Background Contamination - Xerox Phaser 6360 Service Manual

Print-Quality Troubleshooting

Background Contamination

5-24
There is toner contamination on all or most of the page. The contamination
appears as a very light gray dusting. The printer displays no error code.
Note
Depending on the type of paper and environmental conditions, some light
amount of random background spotting (backgrounding) is normal. The
whiter and glossier the paper, the more noticeable it will be.
Initial Actions:
■
Ensure color correction is not set to None in the printer's dialog box.
■
Ask the customer about their typical printing habits. A high daily duty
cycle can temporarily fatigue the OPC drums within the Imaging Unit and
contribute to unwanted background toner.
