Dust on Drum message after installinng new Drum

Since I had been getting "Toner Low" messages when the display told me to "Replace the Drum." Fortunately, I had a new drum on hand. Therefore, I put a new toner cartridge in the drum housing and installed them.

I then got the "Dust on Drum" message. As instructed, I removed the assembly and "cleaned the toner wire," several times, without cancelling the "Dust on Drum" message. I then went to a back-up printer. For several days, I repeated the toner wire routine, without success. Thinking that the new toner cartridge might somehow cause the fault, I put the old one in, but no change.

I then put the OLD drum and new cartridge in, and the DCP7020 proceded to print the cue of stored documents. So I'm limping along with the "old" drum. (Copies look fine!) and keeping my fingers crossed.
Unfortunately, I've had the replacement drum long enough that I can't recall who the supplier was (I think it was Tiger Direct), so swapping with them is not an option.

Any suggestions?

Dust on drum refers to as you correctly stated the wire, it carries a electric charge that transfers the image. If the wire gets contaminated the electricity dont flow right so dust on drum is desplayed, you drum cart is faulty, they are not repairable items, go buy another then claim new/old one as faulty from them. Um aH.

It says drum error but the cart and drum is replaced with new and still can't get past the drum error message.


Hi There!
What you can do to clear the Drum Error message is to clean the corona wire.
  • Open front cover of the machine and remove the drum & toner cartridge assembly.
  • Remove the toner from the drum and gently shake the toner cartridge from side to side put it on a piece of paper to avoid scattering the toner.
  • Theres a blue tab on the upper left side of the drum, slide it from left to right, right to left about 5-6 times don't forget to put the blue tab back to it's home position(where the arrow is).
  • Put the toner back into the drum make sure it will click into place.
  • Reinstall the drum and toner assembly back into the machine and close the front cover.
  • LCD should display the date & time.

If you continue to receive the message try resetting the drum counter by doing the following:
  • Open the front cover
  • Press the Options key on the control panel. The display will show "REPLACE DRUM - 1.YES 2.NO".
  • Press 1 to reset the drum count.
  • Close the front cover
Hope this helps!

We have a Brother MFC-8840D It states that we need to clean the drum - how do we go about that? Turning the machine off and then on it now says that the toner is low. Are these two separate problems or...


t probably told you to clean the drum because it can't sense toner. I would deal with the toner issue first.

You have about 150 prints @ 7% coverage before it won't let you do anything.

I have a Brother fax and copy machine and have just replaced toner with a brother TN 350 cartridge and still getting message that toner is low


You didn't include the model, but here are instructions for the Fax-2820; it should work for any of the models that use the TN-350 toner:
  1. With the power on, open the front cover.
  2. Press the Options key. The display will read "Change Drum?"
  3. Press Start.
  4. Press 1 0.
  5. The display reads "Accepted" for about 2 seconds, then change to "Cover Open."
  6. Close cover. The "Replace toner" message should be cleared.
Normally, inserting a new cartridge (with the power on) will reset the toner counter, and you won't have to do any of this.

Toshiba E-Studio 202L cartridge does not match manufacture


Did you replace the waste (used) toner cartridge or the empty toner cartridge? These copiers have 2 "cartridges" .... one is waste (used) toner, the other is "new" toner for copying / printing etc. Some newer copiers have All in One units....Drum, New Toner, Waste (used) Toner. If you replaced the Waste Toner container (or dumped it) that should reset the code or error message.

HP 2840, black ink drum q3964a


Hello, these printers tend to be finicky.

In other words, just replace the black toner. When the printer says its low, or empty, regardless of wether or not it is, just replace it.

Replacing the drum, when it says black toner needs to be replaced will do nothing to rectify the issue.

Buy only HP Toner and Drum cartridges for this printer. Do not try to refill toner cartridges, and do not reset drum. You will only end up destroying your printer in the process.
