Background Contamination
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 the TekColor 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.
