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.

Leaves black marks on copies


It could be leaking toner from the recovery area that sis on top of the dum, it removes any toner that was not transfered to the paper. You would have to remove it and empty out the toner.

Black lines on copies and on drum


There are a few things you can do to troubleshoot this problem.
  1. Be sure you are using new, clean paper
  2. Clean the copier's paper rollers, the marks may result from a dirty roller mechanism.
  3. Clean the copier bed's glass plate, smudges manifest themselves in the final copies.
  4. Clear any excess toner that has spilled in the toner cartridge chamber. Remove the cartridge, set it aside, then clean the compartment.
  5. Check for low toner levels. Low toner levels can actually contribute to unsightly lines and blotches on a photocopy
If all else fails, try turning down the darkness of the copies in the settings, this can occasionally lead to lines and marks.

I channged toner in my sharp sf-2022 copier, now i have black smudge-like marks going across paper & the copys are real light begin to fade 1/2 way thru page? cleaned 1 of the rollers, helped a little...


Open front cover, you will see yellow knob, pull it down and pullout. Wipe the side with mesh with clean cloth and insert back. That's the main charge unit.
Pull the green lever to the left and pullout the transfer charger . Wipe the two wires carefully not to break them and insert back.

Do not try to remove the drum if you have no skills otherwise this should solve your problem.

I'm sorry to tell you, this is likely a drum issue.

You probably need to have a certified engineer examine the machine.

Have you tried speaking with the local service center to see if they have experienced similar issues? It might be free information.

A smudge across the copy can be in many different areas.
Some ideas.
The drum cleaner may be the problem as you indicate.
It may be a piece of paper ripped of dragging across the surface of the paper causing the smudge.
Also the fuser roll coating may be very worn and causing that.
One thing to try that can show you if the defect is on the drum cartridge, is start to run a copy, After the paper feeds and this is timing, shut the machine off when you think the paper should be about half way through the copy cycle, then see if the copy defect is on the unfused page, If it is smeared before it reaches the fuser, it is in the cleaning section, if it is not smudged, then it is most likely the fuser rollers are needing replaced.
First look for a paper fragment in the path, step 2 is to shut the machine down in mid copy and see if the defect is there.
The fuser is the hot area of the machine in the exit area, If you can take a flash light and look in there and see if you observe wear or heavy toner buildup on a roller then obviously thats the problem.
