Ensure the toner cartridge is an authentic HP product with a genuine HP chip, as the printer's dynamic security system blocks non-compliant circuitry.
Network connectivity is lost or unstable
Check the Ethernet cable connection, verify your router settings, and ensure the printer's IP address has not conflicted with other devices on the network.
Poor image quality or streaking on prints
