Frequently Asked Questions


Will I get the exact number of 7,500 pages with my compatible toner cartridge?

The actual page count varies depending on your average type of document. If your printed pages are more than 5% coverage, it’s most likely that you’ll get less than the approximate page yield.


How is the drum unit different from the toner cartridge?

The toner cartridge acts as the container of the toner powder, while the drum unit is used to create print images on paper.


Why should I take extra caution when putting the toner cartridge in the drum unit?

If you fail to put the toner cartridge correctly in the drum unit, chances are the toner cartridge will separate from the drum unit, which can lead to print quality issues or worse printer damage.
