Color Laserjet 2500n Imaging Drum

Hi,

We have a HP CLJ 2500n printer rattling along here in the office.
It has a very precise countdown on when the imaging drum and toner
should be replaced.
Is there a way, especially for the imaging drum to extend the life a
little bit? There is no deterioration in printing quality of the last
page compared with the first so I get the impression that we are screwed
by HP with this printer.

For Epson inkjet printers there are "chip resetters" to extend the life
of the cartridge. How about something like that for the HP color laserjet?
