Inkjet printers need loving care, especially when it comes to changing cartridges.
Most cartridges have a copper-colored strip that runs down one side.
This is where the cartridge and the printer make electrical contact. You will see a similar area in your printer, and you might find another small area on the cartridge. This is the print head. Any damage to the contacts can cause your printer to malfunction, and something as simple as oil from your skin is all it takes. Care should be taken when installing print cartridges.
