Re: Dust on Drum...

I had this problem too. I took out the drum and vacuum the drum with a vacuum cleaner ( no brush ) while at the same time manually rotate the drum cyclinder. It worked. After a month or two, you might have to do it again. But everytime, it solved the dust problem.

Re: Dust on Drum...

Hi Txguy76,

How many pages did you printed from this drum? If you used this drum over 12,000 printed pages, you should replace with a new drum.

Do you clean corona wire of drum? Take drum out of machine, clean corona wire by gently sliding the blue tab from right to left several times; then, return the blue tab and snap it into the home position (triangle sign). Install toner and drum into your machine and print test.

Good luck to you.

Re: Dust on Drum...

I unpluged the fax/printer, took the drum out. took out the toner Cleaned the drum roller with a damp cloth then dried it very well. Moved that blue tap thing of the drum back and forth a few times. put it all back together and into the machine. Turned it back on. And WOO HOO it finally worked. Thanks for all the tips.

Re: Dust on Drum...

I have had same problem. Try this. Turn off/unplug machine. Take out drum, remove cartridge. Locate the colored roller and insert clean plain paper. Rotate gear to feed paper through. Look at the junk on the paper!. Clean the corona wire by sliding the blue tab thingy as per the manual. Then replace cartridge, drum, turn on machine and hopefully - hey presto!
Good luck.

Step1 Put on your latex gloves to protect the drum from skin oils. Cover a firm, stable working surface with a few sheets of clean newspaper to prevent spreading toner dust over your work area.
Disconnect your Canon copier from its power source and allow it to cool down for several hours if it has been used recently. Locate the access door to your toner cartridge and drum, typically located on the front or side panel depending on your specific model.
Step3 Remove the toner cartridge from its holding tray by lifting from both sides and pulling it up gently. Gently shake the cartridge to remove caked on dust, then place it on top of the newspaper sheets. Using your vacuum's hose attachment, clean away any toner dust from the cartridge's holding tray.
Lift the hinged door behind the holding tray to expose the copier's drum. Turn the spindle to the side of the door to rotate the drum. Apply a microfiber cloth to the outside of the drum as it rotates to clean away toner dust. Continue until the drum is as clean as possible.
Close the hinged door and replace the cartridge in its holding tray, ensuring that it is oriented the same way as when you removed it.
Reconnect your copier to the power source and make a test copy to ensure proper function.

Drum error

Does it say only "drum error", or "dust on drum error" etc?

First try cleaning, this is the easiest and cheapest way.

If this does not help, your drum might be damaged and you need to change it.

When replacing the drum, you might also need to reset the drum counter.

  1. Open the front cover.
  2. Press the Options key on the control panel.
    The display
    will show "REPLACE DRUM - 1.YES 2.NO".
  3. Press 1 to reset the drum count.
  4. Close the front cover.

I have a brother mfc 7820N and it says there is dust on the drum. I have taken it out and blown on it, but I don't know what else to do. It won't print at all! Help!

there is a thin black wire that runs across the drum. Then at the very end of the wire there is a small plastic piece that you could move across the wire that should clean it out.

Drum error. dont have user guide. how do i troubleshoot? tried replacing drum but still says drum error.

If the drum is used up you open the front door and press menu or options and tell it it's a new drum, otherwise you clean the metal contacts on the sides of the drum and inside the printer, and run the blue tab back and forth about 20 times. If still drum error you may have a bad power supply.

I have cleaned the drum but my printer won't work because it keeps saying Dust on Drum. do I ned to replace the drum?

You need to run that blue tab back and forth about 20 times to clean the drum corona, use canned air and blow out the area below the blue tab on the drum, wipe the metal contacts on each side of the drum, and if all that fails, you do need a new drum.

Dust on drum is an issue with the corona wire. Use the blue tab on top of the drum unit. Slide it back and forth 10+ times and this should correct your issue.

Good luck!

Check toner cartridge

Yes to non OEM's and those of you who are using them they cause heap em troubles.

It can be the drum they sit on, or toner dust on contacts of drums, machine base, and toner cart sides , also machine has eyes that get dusty, on machine frame at every toner/drum.
Pull out a tonerlook at side of handle there is a rectangle cut out silver/or black inside this lines up with "eyes" in side of printer frame, clean em.

I have also found a lot of import oki toners going around causing grief too, but fix is always sucessfull by A new gen non import toner and drum and ensuring contacts are free from toner dust.

Another thing I find customers doing is not replacing toners when machine requests them ie at REPLACE TONER, instead they find that just openning and closing lid keeps them going, but these machines hold a complete toner in the drum unit too, so all they are doing is depleting that and when they do finally provide a toner it goes straight into filling up the drum and therefore shortly will display repalce toner again.

Signgirl - your using OEM's so I suspect drum/contacts/eyes what % are t drums at and are they oem too?

Wendy - dont recommend aftermarket/refills all the money you save will be paid to someone like me to come and fix the problems they end up causing.

OKiproblem - ever use aftermarket carts/drum, and what are % of consumables?
