HP recommends that you use genuine HP ink or toner cartridges, as HP cannot guarantee the quality or reliability of non-HP cartridges or refilled HP cartridges.

Some printers, such as HP+ printer models, may require the use of genuine HP cartridges. But even if your printer does not require their use, HP still recommends that you use genuine HP cartridges.

Certain HP printers are intended to work only with cartridges that have a new or reused HP chip or electronic circuitry. These printers use dynamic security measures to block cartridges using a non-HP chip or electronic circuitry. Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked. Original HP cartridges that retain the original HP chip or electronic circuitry enable the refilling, reuse, or remanufacturing of the cartridge and are unaffected by dynamic security.

For more information on dynamic security and how to configure online firmware updates, go to HP Printers - Dynamic Security Enabled Printers.

Also, note that while the use of a non-HP cartridge does not void the HP Limited Warranty or any HP support contract for the printer, any printer or printhead failure or damage that is attributable to the use of a non-HP cartridge will not be covered by the Limited Warranty or any such support contract.

To check the authenticity of a toner cartridge, either use a QR code app to scan the QR code on the toner cartridge box, or go to hp.com/go/ok, type the toner cartridge serial number, and then click Verify.

This toner cartridge is designed for laser printers.
