The printer firmware can then deliver the supply memory error message and the only way to fix this problem is to get the company you purchased the cartridge from to replace it with a new one. One final possible reason for the supply memory error message can be caused when you install a compatible or remanufactured toner cartridge and the data stored on the cartridge microchip is out of date.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 If the software is out of date for any reason, you may get an error.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 microchip 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 replacement 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 as 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 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.
