Brother 6800 light copies and ptints and faxes on brother 6800. I have changed both the drum unit and toner cart twice but the problem comes back after only 5 or 6 copies. I need to know how to make it add more toner per copy. I am not afraid to do what is required to repair, I am trained on ricoh copiers and printers

Clean your laser window on the bottom of the interior of the machine.

The only other common options can be are the contacts of the drum. They can become bent and not give good contact. Bend them back.

When the laser fails it will also become light but it will stay light once it is going.

Check the stupid things - once I had a customer change the toner and not take the tapes off. Had similar symtoms to your problem.

I have a similar black line (about 2inches in width, on the right side) on faxes sent from my Brother 4100e. I cleaned the scanner glass as suggested by you, but it continues to have the same problem on...


Either your machine's
primary corona wire for printing may be dirty, or the sending party's fax scanner may be dirty. Clean
your primary corona wire. I recommend placing the drum unit on a drop cloth or large disposable paper
to avoid spilling and scattering toner.
1. Clean the primary corona wire inside the drum unit by gently sliding the tab from right to left several times.
2. Return the tab and snap it into the Home position, (Caution: If the tab is not at the Home position, printed pages may have vertical stripes).
3. Reinstall the drum unit into the machine.
4. Close the front cover.
5. Plug in the power cord first, and then plug in the telephone cord.
or ask the sender to make a copy to see if the problem is with the sending machine.
Try receiving from another fax machine.
If the problem continues, call Brother Customer
Service at: 1-800-284-4329 (in USA) or 1-877-BROTHER (in Canada)

You can also try these steps below

2 Reset the drum counter if you have already changed the drum recently. Open the device's front cover and press the button labeled "Clear," then close the cover and press the "1" button on the device's control panel.

3 Pull down on the top of the device's front cover. Slide the print cartridge assembly out of the inside of the printer and place it on a scratch piece of paper.

4 Depress the lever on the right side of the assembly and separate the toner cartridge from the drum assembly. Remove the new drum unit from its aluminum bag and snap the toner cartridge into it.

5 Place the print cartridge assembly back into the device and keep the front cover open. Press the "Clear" button, then press "1." Close the front cover once the device's screen reads "Accepted."

We have a Brother HL 2140 series the printer will not print. It has a new toner cart. The drum light is lit . Any suggestions?


This machine has a separate drum and toner cartridge. Replacing the toner does not reset the drum light. Double check that the light on is, in fact, the drum light, and if it is, replace the drum unit. This should resolve your problem.
In order to replace the drum unit, do this: 1) With the printer on and the drum light blinking, open the front cover. 2) Press and hold the Go button for about 4 seconds until all the LEDs light up. Once all LEDs light up, release the Go button. 3) Pull the print assembly out of the machine. 4) Push down the green lock lever to take the toner cartridge out of the drum unit. 5) Put the toner cartridge into the new drum unit. 6) Reinsert the print assembly into the machine. 7) Close the front cover and verify that the lights turn off.
It is theoretically possible that you could reset the counter without actually changing the drum by simply skipping steps 3-6 above, but I have never tried it before and Brother may be checking a chip on the drum unit to verify that it is, in fact, a new drum unit. If they are, you will have to actually replace the unit to make the light go off. I would strongly recommend against resetting the counter without actually changing the drum though, as your print quality will degrade and the machine may start to dump toner into the inside creating a rather large mess and a hefty repair bill.

Brother HL-2040, The drum light keeps coming on and the left side of the printed page is all black?


Sounds like the toner cart. has toner packed at one end and possibly the drum cartridge is dirty. Remove both from the printer, separate the 2 and vacuum the drum cart. - them blow it clean. Run the drum wire cleaner (purple/blue tab on front edge of drum cart.) back & forth a number of times. Blow out the inside of the printer to get out toner dust. Reinstall toner back into drum cart, then hold GO/Control button down until all lights are on, let go, reinstall toner&drum back into printer, close door. Power down - then back on. That should do it. Worst case, you'll have to replace the drum unit.

Drum for Brother MFC-6800 All in One Machine
You can expect it to print 12,000 Page Yield
Whats the difference between a DRUM and a TONER Cartridge? The toner cartridge is a cartridge holding the toner (ink). The drum does the work to transfer the ink to the paper. You will need to replace the drum every 5-6 toner cartridges you use.

Light and streaky copies, and a powder residue.


make sure that the machine is level first. then you will have to change both the drum unit and toner cart with new units not just change the drum in the drum unit.

Printing and copying almost blank pages


Ussally drum/toner would fix, will not be fuser, I would suspect Hi voltage board or laser unit, In australia these machines carry a 2 year return to base warranty.

Try reseting the drum counter, this also resets Bias voltage, might be your problem. open front cover with power on and press set, arrow to change drom and select yes.

Otherwise it would be a high voltage board problem, possibility alsoexist that it could be laser unit

Check status page for "71" errors, menu * 2 8 6 4 very very fast, machine will beep "maintence displays" then 77 to print out status page, 99 to return to normal.

Brother 5240 laser printer changed toner still wont work.


This works on several different Brother Printers to get rid of toner/drum empty errors:

1. Open the front cover and leave open while completing the following steps.
2. Turn the printer off.
3. Hold the 'go' button while turning the printer on. All panel lights should be on.
4. Release the 'go' button.
5. Press the 'go' button 2 times.
6. Pause.
7. Press the 'go' button 5 times.
8. The toner light should be off.
9. The paper light should be on or flashing [doesn't happen on all].
10. Close cover. The ready light should be the only light on.
