Frequently Asked Questions


What do the letters C, M, Y, and K on the left side of the drum units mean?

The letters C, M, Y, and K indicate the colors of the toner cartridge. C is for a cyan cartridge, M is for magenta, Y is for yellow, and K is for black (also known as key).


Is it true that I should insert the new toner cartridge in the drum unit immediately after removing its protective cover?

Yes. Because exposing the cartridge to sunlight or artificial light source for an extended period can lead to print quality issues.


Why should I choose a high yield cartridge for my Brother MFC-9970CDW?

A high yield toner cartridge allows you to print up to two times more pages than standard cartridges while reducing the frequency of replacing cartridges.
