HP printers are designed to work best with genuine HP cartridges, and they often have mechanisms in place to detect refilled or non-HP cartridges. However, there are some steps you can try to get your HP printer to recognize refilled cartridges:

Reset the Cartridges: Turn off the printer and unplug it from the power source. Remove the refilled cartridges and gently clean the contacts on both the cartridge and the printer using a lint-free cloth or cotton swab dipped in distilled water. Allow them to dry completely. Reinsert the cartridges, plug the printer back in, and turn it on.

Use Cartridge Reset Chips: Some refillable cartridges come with reset chips that need to be replace or reset after refilling. Check if your refilled cartridges have such chips and follow the manufacturer’s instructions for resetting them.

Perform a Printer Reset: Turn off the printer and unplug it from the power source. While the printer is unplugged, press and hold the power button for about 15 seconds. Then plug the printer back in and turn it on. This can sometimes reset any internal cartridge detection settings.

Bypass the Cartridge Monitoring: Some HP printers allow you to bypass the cartridge monitoring system. Search for your printer model and “cartridge override” or “cartridge bypass” instructions online. Keep in mind that this might vary depending on your printer model.

Update Firmware/Drivers: Check if there are any firmware updates or driver updates available for your printer model on the official HP website. Sometimes, updates can improve cartridge recognition.

Contact the Refill Service Provider: If you had your cartridges refilled at a third-party refill service. They might be able to provide guidance or solutions to make the cartridges recognizable by your printer.

Check for Printer Compatibility: Some HP printers are more accommodating of refilled cartridges than others. It’s possible that your printer model has limitations when it comes to using refilled cartridges.

Consider Chip Resetters: There are chip resetter devices available in the market that can reset the chip on some refillable cartridges, making them recognizable by the printer. Check if such a device is compatible with your specific cartridges.

Contact HP Support: If none of the above steps work, you might want to contact HP customer support for further assistance. They might have additional recommendations or solutions based on your printer model and the specific refilled cartridges you’re using.

Keep in mind that using refilled cartridges might not always provide the same print quality and reliability as genuine HP cartridges. Additionally, some printers might still reject cartridges despite your efforts. If you continue to face issues, you might consider using genuine HP cartridges to ensure optimal performance and compatibility with your printer.
