Possible reasons for streaks and lines on laser printer pages:

Dirty toner cartridge: A toner cartridge with leaks or uneven toner flow might cause smudges, streaks, or repeated marks on printed documents.

Dirty rollers: Dust, toner residue, or debris on printer rollers can create unwanted lines on your printouts.

Low/uneven toner levels: If toner is low or does not spread evenly, the printed pages may look faded, patchy, or streaky.
