Vertical White Lines

• Vertical white lines are usually due to clogged toner preventing the proper dispersion of toner on the drum. Try shaking the toner cartridge to dislodge the cog. If that doesn’t work, replace the toner cartridge.

Blotchy Print

• This is most commonly due to uneven dispersion of toner, especially if the toner is low. Try shaking the toner from side to side and then try to print. Also be sure that the printer is sitting level. Finally, make sure the paper is not wet in spots.

SPOTTY PRINT

• IF THE SPOTS APPEAR AT REGULAR INTERVALS , THE DRUM MAY BE DAMAGED OR SOME TONER MAYBE STUCK TO THE FUSER ROLLERS.
