If your cartridge has a lever on the left side near the rear, it needs to be reset, and there's a lever inside on the left that can stick and cause that error. You need to wiggle and pull that lever until it moves freely again.

Error message "put the black toner cartridge back in"

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.

How to check the toner level of Brother printer

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.

Dcp 7020 and 7040 toner life end message premature, need override

When the Toner Life End LED flips on, requires you to replace the cartridge, even when there's still toner left in the cartridge. The machine detects end of life by shining a light through from one side to the other.
To circumvent the detection mechanism, remove the cartridge and put a piece of masking tape over or jam a little bit of paper into the clear opening/circle on the right side of the toner cartridge, and then pop the cartridge back in. Eventually, you'll start seeing streaks, and then you'll know that the cartridge is truly empty.
