If you print single page ?

I got this same error message on a newly acquired Brother DCP-7040 that I purchased used off of ebay.

As I was troubleshooting this unit (that I bought untested off of ebay - hey gambling has paid off handsomely for me many times before!), this error message kept popping up.

I checked the COUNTERS (page & Drum life) and found out that the DRUM had 0% life left. BUT, the reason it showed ZERO was because this unit did not have any drum! The toner cartridge (TN-360) needs to sit WITHIN the drum (DR-360) on this DCP-7040 unit, as well as in models DCP-7030, MFC-7340, MFC-7345C, and MFC-7440N.

So perhaps some of these "put the black toner cartridge back in" problems could be related to the DRUM (or lack thereof). A possible tipoff (since the toner cartridge actually does slide into the unit much like other units that do not use Brother's DRUM carrier) seems to be the relative ease with which the toner cartridge slides into the DCP-7040 and really doesn't seem to "lock" into position real firmly.

Sounds like you will need to replace the drum. You can order a drum kit from Grand and Toy or from the Brother website. There are also many other websites you can order a drum kit from. Once the Drum unit is replaced your printer will start working again.

For a cheaper solution you can always reset the drum kit making the printer believe that the drum kit was replaced. For this you might need the manual.

Hope this helps

If your drum is still good - take it out and put it back in - the trick is to LEAVE THE FRONT DOOR OPEN after you put it back in. With the door still OPEN push the "options" button and you will be prompted for "New Drum?" and then push the "Up" button for 'Yes' and "Accepted" will appear on the lcd screen - and then the drum counter will be reset

with the front cover still open press "clear/back." it will ask if you are replacing the drum unit. press the up arrow to indicate yes. wait till it says accepted and then close front cover

It has no accurate measure of the toner left, it is reset when you put in a fresh toner and just counts prints. The Brother shines a light thru a little window from right to left and when the toner is empty the light shines thru and it says it's empty.
