Hewlett-Packard recommends the use of HP products in this printer. Use of nonHP products can cause problems that require service not covered by the Hewlett-Packard warranty or service agreements. Print cartridges and transfer unit It is recommended that you remove the print cartridges and transfer unit when servicing internal printer components. Place the print cartridges and transfer unit in a safe place while they are out of the printer. Grasp the print cartridges by the blue handles to avoid accidentally touching the photosensitive drum inside each cartridge. Do not place any items on the transfer unit or touch the transfer belt. If the belt is punctured or otherwise damaged, print quality problems will result.
