Not long ago, I was asked the question, "Which Brother TN240BK lasts longer, the genuine or the compatible?"
It is understandable a purchaser desiring to get the maximum usage for their purchase.
There could be the following answers such as it depends upon what you are printing, e.g. pictures use a lot more ink than text, or using more color than using black will lessen the usage of black. or even relating to the printer head, which in turn relates to the quality of the toner/ink used.
But the right answer is none of the above!
It depends on the yields offered by the genuine and the compatible TN240BK toner cartridges.
And in each case the rated yield is 2,200 pages, meaning that the one type of TN240BK doesn't out perform the other. Be aware though that each cartridge type will only print approximately 5% of stated yield as according to ISO9001 (International Standards).
If your question though, was "Which Brother TN2150 high yield cartridge runs the longest, the genuine or the compatible?" Then the answer would most definitely be the compatible one (TN2150X) as it has a yield of up to 4,500 pages, as compared to the genuine high yield TN2150 with a yield of 2,600 pages (both ISO ISO9001 Quality Standards).
So the answer is to look at the yield advertised with each printer, remembering that in most, but not all cases the yield for the genuine and the compatible will be the same.
