density • The toner may be unevenly distributed inside the toner
cartridge. Remove the toner cartridge and shake it a few
times to redistribute the toner inside.

cartridge and check it for damage. If the problem persists,
replace the drum cartridge.
Printouts have
irregularities The paper you are using may have absorbed moisture, perhaps
due either to high humidity or water having been spilled on the
paper supply. Toner will not adhere well to wet paper.
Replace the paper with dry paper.
