How to Overide HP Ink Cartridge Expiration Dates

One way to save money on those expensive ink cartridges is to refill them when they are empty instead of buying a new cartridge. However, if the cartridges are for a Hewlett-Packard printer, there's an additional issue. HP printers recognize when a cartridge is empty, but do not recognize a refilled cartridge as being filled, which means it will not allow that refilled cartridge to be used for printing. Removing the printer's battery for a short period can reset the printer, allowing it to recognize refilled cartridges as new cartridges ready for printing.

HP printers can be reset to recognize refilled cartridges as new ones.

Step

Unplug the printer's power cord, and unplug the cord connecting the printer to the computer. This ensures the printer is off and disconnected before removing the battery.

Step

Open the top of the printer, taking care not to scratch or otherwise damage any of the internal pieces.

Step

Locate the battery inside the printer. Its location varies depending on the model of HP printer, but generally it is located in the front lower left section of the printer. It should resemble a small silver disc.

Step

Unplug the battery from the printer by unplugging the small cable attached to it.

Step

Wait about an hour. Reconnect the battery to the printer. After reconnecting the printer to a power outlet and the computer, it should start and recognize a refilled ink cartridge as new.
