Resetting or bypassing the toner cartridge chips

Is there anyone who knows how to reset or bypass the chips on the hp 2840 toner cartridges? I read that on some brands of laserprinters you can disable the toner levels somewhere in the printer setup.I need to just keep on refilling the cartridges w/ bulk toner as long as the print quality remains decent.
None that I know of, however, if you go to ebay there are sellers you sell replacment chips at a reasonable cost which may do the trick for you.

Can I reset the toner on a HP Laserjet 2840? I recently purchased the black toner cartridge and suddenly it said to replace again? I know there is toner left, is there anyway I can simply reset it?

Exchange the chips on yellow toner cartridge and drum ,2840 will show both of them non-hp. Just push check will be done. You can use both of them as long as you like after that.
You can exchange the chip on drum with any one of four color, but can't exchange between four colors. - healthup
