Per HP Manual: The life of the imaging drum depends on the number of black-only or color pages that print. jobs require. An HP color LaserJet 2550 series printer imaging drum could last an average of. 20,000 pages when printing black-only pages and 5,000 pages when printing color pages.
If you buy a new toner for the printer, it will have a chip on it, that limits it to xxxx pages printed, before the printer will refuse to use the toner cartridge any longer. So if you refill that toner cartridge, you need to reset the chip (an easy operation from what I can see on youtube).However-I have the starter cartridge, and that does not have the chip, so I cannot reset it.- but still refuses to use the toner. It would seem there is a different kind of reset mechanism, that needs to be done. have a Samsung ML-1640 laser printer with the starter toner cartridge (that was in it when I bought it). I also bought a toner refill kit and performed the refill.
