Brother Toner Cartridges & Drum Units

How to Replace a Toner Cartridge and Drum Unit in a Brother Laser Printer. 

If you have not replaced the toner cartridge or drum unit in your Brother printer for some time, you may have forgotten the process and how you need to separate the toner cartridge from the drum unit.

Below is our quick guide. We’ll show you how to install both for a selection of popular Brother laser printers. Installation steps do vary slightly depending on the printer and the consumable you are replacing but the process is pretty straightforward once you have an understanding of how the toner and drum unit work.

To begin we will start by reviewing each of the consumables so you know exactly what you are putting in your printer.

A quick look at Brother Toner Cartridges and Drum Units

The toner cartridge and drum unit work together to produce a print. The toner cartridge holds the toner powder and the drum unit is an electrically charged cylinder that transfers that toner powder to paper to create text and images.

Brother sells the toner cartridge and drum unit as two separate consumables. The cartridge fits into the drum unit and both are installed together as one unit into your printer.

Toner cartridges are usually available in a standard yield, high yield and sometimes extra high yield cartridge size. The high yield and extra high yield cartridges do cost a bit more but you will acheive more printed pages which means it is better value in the long term.

Not all Brother printers accept an extra high yield option so be sure to double check your printer manual to verify what your printer will accept.

The drum unit is one size and is compatible with any of the cartridge sizes. Both the toner and drum will need to be replaced overtime, but the toner cartridge will always needing changing first.

There is no requirement to replace the drum each time a toner cartridge is replaced.
