Some HP inkjet printers use cartridges that expire 12 or 24 months after their warranty ends, or 18 or 30 months after being installed in your printer. Some of these printers will refuse to print until you’ve replace an expired cartridge. Other models have an override procedure that you can use to continue printing with an expired ink cartridge. HP will not provide warranty service for any damage to your printer caused by expired ink and warns that old ink and dry cartridges can harm the print head. With these caveats and your budget in mind, overriding the timer is a simple and straightforward procedure.
- Observe the indicator lights on the printer. If you see two blinking lights on the control panel – the “Power” and “Resume” lights – and at least one cartridge light is blinking, it indicates an expired cartridge. Proceed to the next step.
- Press and hold down the “Power” button while you press the “Resume” button three times. The Resume light stops blinking and the cartridge light goes out.
- Continue printing until your cartridge runs out of ink. Monitor your printouts closely and replace the cartridge with a new one if your output quality suffers.
Tips: The date printed on your cartridge represents the end of its warranty period, not its expiration date.
Keep a log that tracks the cartridge installation date and warranty expiration date for each cartridge you use in your HP printer. If you buy HP-brand ink at a local office supply store, check the warranty dates on the boxes and pick the freshest ones available.
Warning: Once you’ve installed a cartridge in your HP printer, do not remove it for more than a few minutes while it still contains ink. An exposed cartridge can dry out and may damage your printer if you reinstall it.
