How to Disable the Timers for HP Ink

All Hewlett Packard ink cartridges have microchips installed that tell the printer when the cartridge expires. HP cartridges typically expire 2 years from their date of manufacture. After this date, the printer will no longer recognize the cartridge. While you can't permanently disable the timers in these cartridges, you can reset them each time you refill a cartridge, or want to use it past its expiration date. A universal method of resetting these timers is to cycle cartridges.

• 1

  Turn on your printer and remove all cartridges.

• 2

  Insert the first cartridge into the printer and allow the printer to verify it. Wait for an alignment page to print , then remove the cartridge.

• 3

  Insert the second cartridge into the printer and allow the printer to verify it. Wait for an alignment page to print, then remove the cartridge.

• 4

  Insert the third cartridge into the printer and allow the printer to verify it. Wait for an alignment page to print, then remove the cartridge.

• 5

  Insert the first cartridge back into the printer. This time, the printer will recognize the cartridge as new and print an alignment page. The ink expiration date is now reset.
