    I have exactly the same problem. I am using a "compatible" non-Brother unit. I bought two. First one worked fine, but this second one does not even get recognized by the unit.

    I have the exact same problem. It happens with a Brother cartridge, too.

Look at the left side of the cartridge next to the blue release button. There should be a white tab in an arc slot. If the white tab is anywhere but all the way to the right, it does not recognize the cartridge. Try truning the drum and pushing the white tab down to the right, it shoudl reset it and find the cartridge.

Brother MFC 7820N, I am getting "Toner End Life"

I fail to see why you are covering up the toner sensor led's when you have a new cartridge fitted?
Also if you are using a recycled toner from a very well known uk shop that refills toners and ink then you may well have broken the drive gear that stirs the toner. i have seen this six times and their toners do this.
It could well be one of the pitfuls of recycled toners.

Brother MFC 7820N Toner life end with new toner

I found the following post on another site. It appears to work. If you want to reset your Brother MFC 7820N machine so you no longer have the error message: Toner End of Life, do the following:

1. Open the front cover of the 7820N, that is, the cover that allows you to pull out the toner and drum, but don't pull out the drum/toner.
2. Push the button: Options (located on the left of the control pad).
3. Type: *00 on the keypad.

The Brother MFC 7820N should be reset and the Toner End of Life message should disappear. WARNING: This may void your warranty and ultimately damage your machine if you are reusing or refilling your cartridges, but you should already know that. Hope this helps.

Brother MFC 7820N Printed paper has toner ink layered on paper

you can remove the toner and drum from the machine, slide the tab back and forth about 20 times then blow in the slot. when you put it back in the machine if the problem keeps happening it would be a problem with the toner cartridge and it would need to be replaced

the reason this happens to toner cartridges is because the rubber roller tarts to wear out.

Hi There,

When you installed your new drum did you reset the drum by.

1 - Opening the front cover.
2 - Press the options button up on the panel.
3 - Press 1 to reset
4 - Close the front cover done.

If the issue persists after resetting your drum contact brother technical support you may have a defective drum unit.

you take the toner and drum assembly out of the printer, set it on a level surface, press the blue lever on the left side rear, and lift and remove the toner. Remove any packing material from the new cartridge, set the front toward the drum in first and lower the rear down until the blue lever clicks. Re-install the assembly into the printer...good to go!
