Replace the transfer kit.
If the imaging drum is near end of life, replace it.

improperly.

cartridge.

Irregular, raised streaks
To diagnose this print quality problem, lay the printed page on a hard
smooth surface, and feel the streaks of toner. The spots or streaks will
not look raised, but will feel raised to the touch.
Make sure that all media is cleared from the paper path (see
page 176).
The fuser roller is damaged. Replace the fuser kit.
If one toner color is streaking, that toner cartridge has been
damaged. Replace the toner cartridge for the streaking color.
