One final possible reason for the supplies memory error message can be caused when you install a compatible or remanufactured toner cartridge and the data stored on the cartridge micro chip is out of date. You can find the latest firmware updates on the HP website here. Once updated this can often fix many printer problems. Visit google and type ‘ firmware’ in the search bar and download the latest one for your computer / printer. If the software is out of date for any reason, you may get an error.

Your printer manufacturer will regularly update your printer with new software of firmware. Also if using a remanufactured cartridge, double check that the micro chip is securely in position, isn’t dirty and that nothing is obscuring it. It’s also possible that losing bits of packing material or paper jams can cause an issue so make sure the printer is clear before installing a new toner. This should allow them to correctly connect to the toner once you install it again. If the two metal connectors seem squashed back, gently (so not to break anything), pull them forwards. Now visualise where these would connect inside the printer and look for the corresponding connectors inside the printer (making sure the printer is switched off and unplugged). Remove your toner cartridge and have a look for something that resembles a microchip or two metal squares. If the contacts aren’t touching, your printer will think that the toner isn’t installed. The metal contacts in the printer and the ones on the toner complete a circuit.
So a printer can detect a toner cartridge that has been installed, 2 tiny metal contacts must connect to the corresponding contacts on the cartridge.
