When do I replace a Brother drum unit?
The DR-730 drum has a yield of approximately 12,000 pages and typically needs to be replaced after the use of 3 or 4 toner cartridges . If you own a Brother laser printer and you are getting a “Replace Drum” message on your machine’s display, it might be time to get a new drum.

How to Replace the DR-730 Drum Unit
Before you replace the new drum, you’ll need to take the current drum out of the printer. It is important note – even though the drum needs to be replaced, you do not need to replace the toner cartridge at the same time. If you have a working toner cartridge already installed in the printer, you can use that same toner cartridge with the new drum. Check out our replacement video below, or keep reading to follow the process step by step.
The first thing you will want to do is open up the door to access the drum unit. For this Brother printer series, the cartridge is actually sitting in the drum unit, so you’ll need to take out the entire unit in order to separate the cartridge from the drum. It all comes out in one piece, just gently pull up and out and it should come right out. There is a green tab that keeps that keeps the toner cartridge locked into place. To remove the toner from the drum unit, pull up on the tab with your thumb and the cartridge can be removed.
Next, insert that same toner cartridge into your new drum unit, it should click into place. Once it is secure, we recommend sliding the green tab from left to right a couple of times, this cleans the corona wire and helps prime the cartridge and drum unit for the printer. Be sure to return that tab to the original position when you are done. Then, slide the entire unit back into the printer and close up the cover.
Before you start printing you will need to reset the drum counter – we show you how in the next section!
