First check if the cartridge is the correct model for your printer

Take the cartridge out of the printer and check all the packaging has been removed from the cartridges

When the printer is still on, pull the power cable out the back of the printer and leave the printer off for 15 minutes. This process is to reset the printer memory

If the cartridge contains a micro chip, while the cartridge is out of the printer give the chip a good wipe with a tissue or cloth.

Ensure that the inside of the printer is clean and that there are no sensors that have been covered with toner powder.

Wait for at least 15 minutes and then turn the printer back on and insert the cartridge, making sure that it is clicked firmly into place in the slot within the printer

This will reset the printer and in most cases it will resolve the issue.
