Once the headrest is released, simply pull it out of the seat and insert the new headrest by aligning the metal rods with the slots in the seat and pushing it in until it clicks into place. Finally, adjust the new headrest to the desired position. **

Secondly, the ink cartridge may be incompatible with the printer model. Lastly, there could be a problem with the printer's software or firmware that is preventing it from recognizing the ink cartridge.
