Installation Notes

Power the printer on before replacing the cartridge, as most HP inkjet printers require the carriage to move to the access position during an active power cycle. Remove the old cartridge and install the replacement firmly until it clicks into place. Avoid touching the ink nozzle or electrical contacts on the cartridge. Follow the printer manufacturer's alignment and purge routine after installation to ensure consistent output quality.
