Most cartridges have either 7 or 9 pinholes in a cluster. Compare a picture of the pins on the reset tool to the number and arrangement of pinholes on the bottom of your print cartridge before purchasing. If you don’t see a cluster of pinholes, look for a small green microchip somewhere on the cartridge—it will either have one single pinhole just above or below it, or two round metal contacts at the top or bottom. [1] X Research source In this case, see the Using a Paperclip method. “Universal” chip reset tools are NOT universal for all models—some tools marked as “Universal” have 7 pins, while others have 9.
If you have a cluster of 7 to 9 pinholes instead, see this method.
This will only work if the chip in the other cartridge is not also out of ink. You can also use a chip from another matching cartridge for your model.
Be sure to keep track of which chip came from which cartridge—if you put the same chip back into the same cartridge, the chip will not reset.
If you have an Ink Change button, press it again once the printer is ready before you continue.
