"Transfer Roller and Fuser
Assembly" on page 331.
4 Does the imaging quality improve if
the Transfer Roller is replaced?
5 Check the following pins to the
transfer roller contacts for continuity:
J5030 <=> Transfer Roller
J5020 <=> Transfer Roller

Troubleshooting
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. Before using this procedure,
Ensure the TekColor Correction is not set to
"None" in the printer's dialog box. Ensure
the customer is making less than 2,000
prints per day. Making more than 2,000
prints a day exceeds the duty cycle
specifications for the printer.
