Drum cartridge My status screen said drum cartridge end of life. I replaced the drum cartridge and my black toner was also empty. So now I am trying to replace the black toner but when I select replace black toner from the menu it says please wait but never does anything, to get that off of the screen I have to turn it off and back on again.

Some Brother laser printers have separate consumables - the toner cartridge and the drum unit. From time to time you may need to replace only the drum unit and not the toner cartridge.

The error LED lights up, or an error message shows on a flat screen panel, when the drum unit is near the end of its working life. Use the drum unit until you have a print quality problem, then replace the drum unit with a new one.

Brother strongly recommends that customers use only genuine Brother drum units and/or toner cartridges. Each Brother laser printer is designed to work at pre-set temperatures that are matched exactly to each of our individual toner formulations. Each individual component is designed to work with the other to ensure quality and reliability. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability. The Brother limited warranty does not apply to any problem that is caused by the use of third party drum units, toner cartridges or toner.

1. Verify you installed a NEW, out of the box, genuine Brother toner cartridge (TN360/TN330).

If a toner cartridge from another machine was installed (even if there?s still toner left in the used cartridge) or a starter toner cartridge (included with the purchase of a machine) was installed, the Toner LED will stay on and the message "Toner Life End" would continue to appear on the display.

2. Verify the toner cartridge is installed correctly by following the steps listed below:

a. Open the front cover by pulling the tabs on the left and right side of the printer towards you.

b. Lift the drum unit slightly and pull it out. Place the drum unit on a piece of disposable paper or cloth to avoid spilling and scattering the toner.

c. Remove the toner cartridge from the drum by holding down the lock lever (blue tab) on the left side of the drum unit and lift the toner out. Handle the toner cartridge carefully. If toner scatters on your hands or clothes, immediately wash it off with cold water.

d. Gently rock the toner cartridge from side to side five or six times to distribute the toner evenly inside the cartridge.

e. Place the toner cartridge into the drum (be sure it clicks into place).

f. Clean the primary corona wire inside the drum unit by gently sliding the blue tab on the top of the cartridge from right to left several times. Return the blue tab to the home position before reinstalling the drum unit assembly.

g. Reseat the drum unit into the printer pressing it in securely.

h. Close the front cover making sure it latches on both sides.

If the Toner LED is still on or the status monitor continues to display the message "Toner Life End" the printer will need service.

The printer has a one year limited exchange warranty. If the printer is in warranty, call Brother Customer Service at 1-877-Brother (1-877-276-8437) for warranty options.

If the printer is out of warranty, contact a Brother Authorized Service Center for repair by clicking on the link below:

After I figured this out, it was quite easy to resolve. Remove the toner cartridge from the drum cartridge. Remove the black plastic cover on the left side of the toner cartridge (3 Phillips screws). There is a "flag", which is a small plastic tab on the outer side set to the right at about 2 o'clock. Turn the gears until you fully reset the tab going counterclockwise to the 10 o'clock position (fully to the left). Reinstall the small black cover and the three phillips screws. And the idea to install black electrical tape over the small clear plastic windows on both sides is also a good idea to prevent the early and false message that the cartridge is empty. Make sure you do not allow that tape to get into the gears.

In this case, actually it is not the Black toner that got depleted. Here the message being displayed indicate that one of the color Toner supply need to be replaced as it got depleted and currently the printer is printing in Black and white using the Black toner cartridge.

in this case, to troubleshoot these issues please try performing the following and check for the results.

* 1. Check for the level of the toner cartridges:

a) Check from the HP Toolbox application. Here are the steps to be performed from your PC:

* Access the Toolbox software.
* Select the Status tab.
* Select the Device status option.

Here you can check for the supplies status in terms of the % remaining for each toner cartridges.

b) By checking the supplies status from the printer control panel display.

On the printer display when printer is in Ready mode the supplies status can be checked from the supplies level indicator. Each toner cartridge and the Imaging drum level will be indicated by a bar which varies according to the level of the supplies present.

c) Print the supplies status page from the printer.

* On the printer control panel menu, press Menu .
* Use the (Right Arrow) button to select Reports, and then press Enter .
* Use the (Right Arrow) button to select Supplies Status, and then press Enter .

If any of the color toner cartridges and the Imaging drum have a low supply level replace them with genuine HP print cartridges.

The part numbers of the consumables are as follows:

* Black print cartridge - Q3960A
* Cyan print cartridge - Q3971A
* Magenta print cartridge - Q3973A
* Yellow print cartridge - Q3972A
* Imaging Drum - Q3964A

Instead of following the directions as outlined in the manual, to have the printer turn the drum so I could extract the empty cartridge, I cut out a couple steps, by just reading the printers status display window. Followed the links that took me to where it said Replace Empty Toner Black, pressed the Menu Select button, and was given the OK to open the lid and door and replace the empty cartridge.

The toner is the black powder which the printer uses to turn type and pictures into a printed piece. The drum is the device that actually fuses the image to the paper. Toner cartridges and drums have a service life. Toner cartridges will have say a 3000 sheet capacity. When it is empty you replace it. The drum will have a 10-20,000 sheet capacity. Typically the drum is three to four times more expensive to replace. Many companies will give you a credit for turning them in vs ending up in a landfill.
Good luck.

that error usually indicates that the toner has reached its end of life
or the drum is not properly installed.

i had one person who put the toner in but threw the drum cartridge away.

Toner probably isn't empty, but the machine shuts down at a specifc count on the cartridge regardless of actual consumption...don't you love it?
Your replacement cartridge was probably a remanufactured one and didn't have the toner reset lever properly set.

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.

I have a brother mfc 7840w

I first used the electrical tape trick and that worked for a while. Then got the toner low message again. I then tried the *00 trick, which works as follows:

1. lift lid and open front cover
2. press clear/back. "Replace Drum?" will appear on the screen.
3. Press "*00" it will then read accepted and the toner low error (End of Toner Life) should go away.
4. close it all up and your done.
