Replace Your Toner Cartridge and a Drum Unit in a Brother Laser Printer by the Following Steps

If you are a newbie to replacing the toner cartridge or a drum unit in the Brother printer, this might be a little challenging for you. In this handy guide, we will enlighten you to install both the Brother laser printer.


The toner cartridge and the 123ink brother drum unit work together to give out a print. The former is the container that stores the toner powder and the latter is an electrically charged cylinder that shifts the toner powder to the paper in order to create text and images. Both of these components are sold as separate units. The cartridge is designed in such a way that it fits the drum and both are installed together as a single unit in the printer.

Toner can be provided in a standard yield, high yield, and an extra high yield cartridge size. The high yield and the extra high yield are expensive but have a huge page yield as an overall value. Not all Brother Printers have an extra high yield variety so ensure to consult your printer manual to verify what is valid for your machine. The drum unit is available in a single size and works with any of the aforementioned cartridge sizes. Both the toner as well as the drum need to be replaced in the end but the toner cartridge is always the first one to be considered.

When to replace a toner cartridge?

A toner cartridge needs replacement when it touches the determined page yield or the approximate amount of pages that can be printed with a particular cartridge. You can find the page yield on the cartridge box or on the manufacturer’s website. It will help you in determining when it is the right time to replace the toner with a toner low or replace toner message on the printer display.

When to replace the drum unit?

The drum unit is designed in such a way that it lasts longer and usually should be replaced after 3 to 4 toners have been used. Brother always keeps a track of the drum life by counting the frequency of the rotations of the drum. When a drum is about to reach the determined rotation limit to the page yield, a message like ‘drum life end soon’ will be displayed on your printer. When it comes to installing a new drum unit for the very first time, you will be required to reset the drum counter in order to restart the rotation count on your printer.
