If you have tried a new drum unit (DR-2025) without success, you will most likely find that the ghosting is caused by a worn roller in the fuser unit.

A brother service centre would be able to replace the roller or the entire fuser for you, but it may be expensive. Compare prices on a new replacement machine - brother MFC-7340.

Hi there,

Below are instructions that I have found from the internet. Hope that they will help.

  • Open the front cover of the printer.
  • Hold down the Go button for 4 seconds until all the LEDs light up. Then release the Go button
  • Remove the drum unit and toner cartridge assembly.
  • Replace the drum unit and toner cartridge assembly back into the printer.
  • Close the front cover of the printer
  • Your drum unit should now be reset
  • MFC / DCP PRINTER SERIES

    1.Remove the drum unit and toner cartridge. Wait 1 or 2 minutes.
    2.Replace the drum unit and toner cartridge into printer.
    3.The error message "Change Drum Soon/Drum end soon" will continue to appear if the drum counter was not reset when you replace the drum unit.
    4.To clear this error message, you need to reset the drum counter as instructed below.
    5.Make sure that the machine is turned on.

    For MFC users: To confirm you are installing a new drum, press 1. For DCP users To confirm you are installing a new drum, press the Up Arrow key

    7.When the LCD shows Accepted, close the front cover.
    8.Your drum is now reset.

    Resetting the drum unit will not improve print quality. It only resets your drum and allows you to continue to print. You decide when to replace the drum unit not the manufacturer!

Ghost image on a hp CM1415


Two reasons for ghost image
1. Toner cartridge faulty.
There is a part in toner cartridge called Drum cleaner (also called as tractor blade), if this part not clean the drum surface properly ghost image will form on drum & it will transfers on paper..
2. Fuser assm faulty.
There is a part in fuser assembly called Teflon sleeve. If toner particles deposited on teflon sleeve you may get ghost image..

Ghost writing on my Brother DCP-7030 all in one printer


Ghosting on machines can be one of several causes.



  1. Poor Quality/ Damp toner - Replace the toner cartridge


  2. Worn Drum Unit - Replace the Drum Unit


  3. Fuser Unit Failing - Replace the Fuser Unit (Normally more than the printer is worth).


  4. Damp Paper - Open a new ream of paper and try printing again (This is the cheapest option to start with diagnosis).

Dell 3100 printer ghosting


Ghosting can be caused by two things. Either too much toner is being laid down which incurs a starvation of it. Or, the image is being repeated due to a problem with the drum. In your case, I want it to be the "too much toner" deal, because a drum replacement can definitely be more costly in comparison to a design change. Yet, if it is under warranty, the drum will be replaced at no cost.
