Disassemble the cylinder of the image unit and review if the gears of the recycled of toner were not damaged, you accustom they are broken and they caused that the blade fails to be saturated of toner that section. If it is thus it also cleans with a vacuum cleaner the bushings of the spiral and the overturned trowel of until they are light. This does that all the values of feeding of toner behave of irregular way until saturating the developer.

Sir, I am getting black patch on right side of the paper when I take xerox. Please reply


Hi,
is these black patch like the toner isnt baked and it peels of the paper?

If yes, you have problem in fixing section, probably fixing rollers bushing.

Also remove the drum unit and check drum for toner leftovers. If the drum is covered with toner after copieing replace drum unit.

Hope that helps!

THERE ARE LARGE STREAKS OF INK ON ALL COPIES AND


The green roller is the drum which has a cleaning blade to remove excess toner, when the drum gets older it becomes clogged and will dump toner back out onto the drum. Just some info on it. Best fix is replace the drum, you could take it apart and attempt to dump and clean it but it's rarely worth doing that.

Copy light


Hi

When you were replacing the drum did you tuch the drum surface?Best would be that you take some toner on piece of cloth, and polish the drum, while turning it in good direction, that the cleaning blade can clean it.After you must let it copy about 50 copies.

You can try to replace the whole drum unit cexv14, or clean the laser unit.

Also could it be that the toner unit, or toner cleaning blade are not properly distibutes the toner accross the developing/toner cylinder.

After changing toner on my sharp, SF-2022 copy machine, the copies are coming out with black smudge marks across the paper? how/where should i clean?


This means the machine is over-toning ie using more toner than required caused by either improper toner or different brand of toner. The correct toner is sf 222T1. Replace developer and use the right toner and clean the drum and its blade. You may need to clean fuser rollers for cleaner copies.
