Product Description
Brother MFC-8640N Drum Unit -25,000Pages (Brother MFC8640N Drum)

This Drum is good for printing 25000 pages, on average. Average page coverage is 5% of toner per page (compared to white space on the paper), which is the standard Brother specification for this drum, and a standard measuring term for the consumer printing industry.


This product comes with a 6 month Warranty against any defects (including free replacement). We stand behind our products 100%, as these are not manufactured by Brother.

What's the difference between a drum and a toner cartridge? A toner cartridge is just that: a cartridge that contains toner. The drum does all the work.


Product Manuals
When do I Replace a Drum Unit in the Brother MFC-8640N Multifunction Center?
The drum unit is a consumable component that has to be replaced periodically (after approx. 20,000 A4 pages at 5% coverage). The actual drum life depends on various factors, such as printing environmental conditions, type of paper, size of paper, and percentage of page coverage. You can check the drum life counter from the control panel by selecting [2. Fax] – [0. Miscellaneous] – [Drum Life].
You should replace the installed drum unit when/if:

The message [Change Drum Soon] is displayed – Print quality cannot be guaranteed because the installed drum unit has reached the replacement threshold. You should replace the installed drum unit if/when print quality is/become unsatisfactory.

One or several of the listed print quality problems occur(s). Please note that you can solve some print quality problems by cleaning the primary corona wire of the drum unit (Please refer to ‘’How to Install a Toner Cartridge in the Brother MFC-8640N Multifunction Center’’).
