HL-5240 Appears to need new toner but that didn't fix it.
If the marks on the page appear to repeat three or four times down the page regardless of what is printed, it could be the drum unit ( the unit the cartridge fits into) You can test this by taking the cartridge out of the drum and looking at the cylinder in the drum unit. If has light coloured bands, or looks very black, then it is at or past its life cycle ca20-25k pages. If it has clots of toner stuck to it but is otherwise ok, you could carefully clean it with alcohol and a cotton ball to remove the toner clots. Steady and patient is more rewarding than trying to grind the stuff off. If the drum looks reasonably clean, open the flap at the back of the printer and look closely at the fuser. If there are clots of toner stuck to the orange pressure roller or to the grey/tan fuser roller, then the fuser will need to be taken out and cleaned also with alcohol, cotton ball and much patience.
