It seems to me that the HP Ink Advantage 2545 printers do not have any locks to the cartridges of the ink cartridges. If there is a problem with the ink, remove the container and clean the contacts, eg with a pencil eraser, and re-insert the container. If the dry container is topped up with ink using a syringe. This should help if you do not need to buy, for example, a black ink cartridge CZ 101AE HP650 (in the price of about PLN 35) and after the trouble.
