Print-Quality Troubleshooting
Repeating and/or Random Spots
Spots of toner are randomly scattered across the page or at a fixed repeating
interval.
Initial Actions
■ Verify the Imaging Unit and Transfer Roller are not at or near end of life.
Waste toner especially from the Transfer Roller can cause random spots
to appear on the page.
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.
