information about the CSR program and benefits can be found at www.hp.com/go/csr-support and

Genuine HP replacement parts can be ordered at www.hp.com/buy/parts or by contacting an HP-authorized
service or support provider. When ordering, one of the following will be needed: part number, serial number
(found on back of printer), product number, or printer name.
● Parts listed as Mandatory self-replacement are to be installed by customers, unless you are willing to pay

provided under the HP printer warranty.
● Parts listed as Optional self-replacement can be installed by HP service personnel at your request for no
additional charge during the printer warranty period.
