We have an HP LaserJet P4515 printer and we only use 64X cartridges with it.
We've had the printer since 2012 and the average yield of the cartridge (before the quality becomes unacceptable) is around 47,000 pages.
Problem is, the cartridges report that they are at 0% toner after around 24,000 pages which creates a confusion.
Is there anyway to fix that?!
