What do I do when the cartridge light blinks and the printer won't print? There are some causes to this problem. Either the cover isn't well shut, you are out of ink, or look for a yellow indicator arrow on the cartridge. Also, the carts don't sit right, or have a bad connection due to dried ink on the contacts.
