When the error message "supply memory error" appear on your HP printer, please follow the step to fix it.

  1. Lose packaging or protective strips

When you’re about to install a new toner cartridge, there are orange protective strips and plastic clips that are there to make sure the cartridge isn’t damaged whilst being transported. Each of these clips and protective strip across the drum must be removed before installing your new toner, otherwise they will prevent your printer from printing


Clips are easy to spot and stick out like a sore thumb, the protective strip is on the side of the toner and has an orange ring that must be pulled to remove the strip or will like like a piece of cellophane as it does in the image below.


  1. Squashed Metal contacts

For your printer to be able to detect a toner cartridge that has been installed, 2 tiny metal contacts much connect to the corresponding contacts on the cartridge. The metal contacts in the printer, and the ones on the toner complete a circuit and if the contacts aren’t touching. Your printer will think that the toner isn’t installed.

Remove your toner cartridge and have a look for something that resembles a microchip or two metal squares. 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).

If the two metal connectors seem squashed back, gently (so not to break anything), pull them forwards. This should allow them to correctly connect to the toner once you install it again.

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.


  1. Broken plastic pieces

If a toner cartridge has been damaged along one of the sides so that the plastic slots have broken off then it may not correctly sit inside the printer and similarly to the previous reason for the supplies memory issue, the contacts won’t correctly connect, and the only way to fix this problem is to replace the toner cartridge with a new one.


  1. Out of date firmware / software

Your printer manufacturer will regularly update your printer with new software of firmware. If this software is out of date for any reason, you may get an error. Visit google and type ‘[your printer model] firmware’ in the search bar and download the latest one for your computer / printer. Once updated this can often fix many printer problems. You can find the latest firmware updates on the HP website.

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 cartridges micro chip is out of date.

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 reman from to replace it with a new one and  then swap it out in your printer.

There you have it, hopefully these tips have been helpful and your printer is working again.
