Installation Notes

Power on the printer before replacing the cartridge, as most HP Officejet Pro X-series models require the carriage to be in the home position for safe access. Remove the cartridge from its packaging just before installation to avoid exposing the ink nozzles to air unnecessarily. Follow the printer manufacturer's cartridge replacement procedure and dispose of the used cartridge in accordance with local regulations for ink and electronics waste.
