You may follow the steps suggested in this support document to clean the ink cartridge contacts - HP Printers - 'Incompatible Ink Cartridge' or 'Ink Cartridges Missing' Error Displays Turn on the printer and wait till warm-up period finishes and the printer is idle. Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer. Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet. If the issue persists, I would suggest here is to do a hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector. Alternatively you can also try to update the printer firmware directly from the printer control panel.įor more details on how to update, please use this link: HP Printers - Updating or Upgrading Printer Firmware If your printer connected wirelessly, make sure to temporary connect the device with USB and then follow the link to install the latest firmware update on your printer from our HP support website.

In this scenario, you could try to update the printer firmware and check if that helps.

HP cannot guarantee the quality or reliability of non-HP or refilled cartridges. HP recommends that you use genuine HP ink or toner supplies. If a refilled cartridge does break your printer, it also voids the warranty. Refilled cartridges can leak and clog the printer head, while this may not break the printer outright, it increases the risk of damage to your printer.
