If your Brother DCP-1510 or DCP-1512 shows a “Replace Drum” or “Drum End Soon” message after you fit a new drum unit, you need to reset the drum counter. This guide covers two ways to do a Brother DCP-1510 drum reset — the standard menu method, and an alternative method if the first one does not work.
The Brother machine has two separate consumables: the toner cartridge and the drum unit. Make sure you have replaced the drum unit (not the toner) and that the machine is powered on.

To be sure, switch the printer off and on. If you see “Printer is busy” after the reset step, switching the printer off and on usually clears it.
Try Method 1 first — it is the standard reset after replacing the drum. Use Method 2 only if the standard menu reset does not clear the message.
No. This resets only the drum counter. The toner cartridge has its own separate reset.
The drum on the DCP-1510/1512 is rated for roughly 10,000 pages, depending on usage.
