Hi,

The drum unit transfers the toner into an image onto a drum, which the paper is fed through to pick up.

Some printers have the drum unit integral with the toner cartridges (as in the HP 5L & 6L). Others require you to buy a separate unit (as in the Dell 3100 series).

The more technical description is here:
Initially, the drum is given a total positive charge by the charge corona wire, a wire with an electrical current running through it. (Some printers use a charged roller instead of a corona wire, but the principle is the same.) As the drum revolves, the printer shines a tiny laser beam across the surface to discharge certain points. In this way, the laser "draws" the letters and images to be printed as a pattern of electrical charges -- an electrostatic image. The system can also work with the charges reversed -- that is, a positive electrostatic image on a negative background. Please post your feedback and Vote if the problem resolved as per your satisfaction.

I HAVE REPLACED TONER WITH THE CORRECT BROTHER TONER CARRTRIDGE AND THE MACHINE KEEPS TELLING ME TONER ERROR AND REINSTALL DRUM UNIT..HELP


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!

How do I take out the drum


When you change the toner cartridges you have to take out the whole Drum and Toner unit and unclip the toner from the drum unit. The Drum when you are replacing it is the DR7000 unit. Replace this unit and clip your toner unit back onto the new drum unit and re-install it in the printer and follow the instructions that came with the replacement drum unit to reset the drum counter.

I have a HL4040CDN it said the Cyan was out and we replaced it with a new one and it says the same thing. Checked and found no problem.

If you have print quality problems, clean the drum unit as follows:

1.Turn off the printer power switch. Press the front cover release button and then open the front cover.

2.Hold the green handle of the drum unit. Lift the drum unit up and then pull it out until it stops.

3.Release the gray lock lever (1) that is on the left side of the printer. Pull the drum unit completely out of the printer using the green handles on the drum unit.

  • We recommend that you place the drum unit on a clean, flat surface with a piece of disposable paper underneath it in case you accidentally spill or scatter toner.
  • Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
  • Hold the handles of the drum unit when you carry it. DO NOT hold the sides of the drum unit.
4.Hold the handle of the toner cartridge and pull it out of the drum unit. Repeat this for all the toner cartridges.

5.Turn the drum unit over by holding the handle. Make sure that the four drum unit gears are on the left side and the drum unit gear "1" is located furthest away from you. The numbers can be found on the drum unit gear.

We recommend that you place the drum unit on a clean, flat surface with a piece of disposable paper underneath it in case you accidentally spill or scatter toner.

6.See the print sample to identify the color causing the problem. The color of the spots is the color of the drum you should clean. For example, if the spots are cyan, you should clean the drum for cyan. Put the print sample in front of the drum, and find the exact position of the poor print.

7.Turn the drum unit gear toward you by hand while looking at the surface of the drum (1).

8.When you have found the mark on the drum that matches the print sample, hold the middle of a cotton swab and wipe the surface of the drum gently until the dust or paper powder on the surface comes off.

Caution DO NOT clean the surface of the photosensitive drum with a sharp object.

9.Turn the drum unit gear toward you by hand to return it to the home position. The home position of each drum can be identified by matching the number on the drum unit gear to the same number on the left side of the drum unit.

10.Make sure that the number on each of the four drum unit gears matches the corresponding number on the side of the drum unit.

11.Using the green handles turn the drum unit back over.

12.Hold the handle of the toner cartridge and slide the toner cartridge into the drum unit. Make sure that you match the toner cartridge color to the same color label on the drum unit, and make sure that you fold down the toner cartridge handle (1) once the toner cartridge is in place. Repeat this for all the toner cartridges.

13.Put the drum unit back in the printer as follows.
  1. Make sure that the gray lock lever (1) is in the up position and put the drum unit in the printer. Push down the gray lock lever (1).
When you put the drum unit in the printer, match the green guides (1) of the drum unit handle to the green arrows (2) on both sides of the machine.

2.Push the drum unit in until it stops.

14.Close the front cover.
