Warranty Note The warranty outlines specific legal rights. There might also be other rights that vary from area to area. Refer to the user's guide for further warranty information. Installation Installation by service personnel is included with the HP Color LaserJet 8500 DN printer and is required with the HP Color LaserJet 8550 MFP. Installation is optional with all other models of HP Color LaserJet 8500 and 8550 models. Installation can be arranged through the Customer Care Center. Toner cartridge information The toner cartridge is designed to simplify replacement of the major "consumable" parts. The toner cartridge contains part of the printing mechanism and a supply of toner. For best results, always use a toner cartridge before the expiration date stamped on the toner cartridge box. Refilled toner cartridges While HP does not prohibit the use of refilled toner cartridges during the warranty period or while the printer is under a maintenance contract, it is not recommended for the following reasons:
Repairs resulting from the use of refilled toner cartridges are not covered under HP warranty or maintenance contracts.
HP has no control or process to ensure that a refilled toner cartridge functions at the high level of reliability of a new HP LaserJet toner cartridge. HP also cannot predict what the long-term reliability effect on the printer is from using different toner formulations found in refilled cartridges.
The print quality of HP LaserJet toner cartridges influences the customer's perception of the printer. HP has no control over the actual print quality produced by a refilled toner cartridge. EN Warranty 69
