• Check that the cartridge being used is the correct one for your printer model.
• Check that the cartridge is inserted in the correct orientation.
• Check that all protective elements which may impede insertion have been removed from the cartridge (protective caps or tabs).
There are two types of cartridge: “remanufactured” ink jet cartridges and compatible cartridges.
• While compatible cartridges are different from genuine cartridges, they are specifically designed to fit into your printer.
• Remanufactured cartridges are genuine cartridges which have been recycled and therefore have exactly the same dimensions as genuine cartridges.
