back of the page.

• Toner is on the transfer roller. To help prevent this, do not load
print media that is smaller than the page size of the job to be
printed. Specify the correct page size in your driver or in the
Local Printer Setup Utility. For more information, see

the Local Printer Setup Utility

• To clean the transfer roller, open and close the printer upper
front door. The printer automatically runs its setup cycle.
