Why the cartridge won’t snap into place?
My cartridge model is HP564
Solution: If you are trying to install your cartridge and it won’t click down in the machine, then the tab on the cartridge may be bent too far toward the cartridge body. The tab is the little plastic tail that juts off of the end of the cartridge. Bend down on the tab a few times so it forms a 45 degree angle, then reinstall. It should now click in smoothly.
