*The LLC life test conditions: ● Print coverage: 5% evenly distributed across the page ● Environment: 17° to 25°C (62.6° to 77°F); 30%-70% relative humidity (RH) ● Media size: Letter/A4 ● Media weight: 75 g/m2 (20 lb) plain media ● Job size: 4 pages or more on average ● Long-edge feed (Letter/A4) Factors that can reduce life from the conditions above: ● Media narrower than Letter/A4 widths (thermal slowdowns equal more rotations) ● Paper heavier than 75 g/m2 (20 lb) (heavier media creates higher stress on printer components) ● Print jobs smaller than 4 pages (smaller jobs mean more thermal cycling and more rotations) Customer self-repair parts Customer Self-Repair (CSR) parts are available for many HP LaserJet printers to reduce repair time. NOTE: More information about the CSR program and benefits can be found at www.hp.com/go/csr-support and www.hp.com/go/csr-faq. 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 HP service personnel to perform the repair. For these parts, on-site or return-to-depot support is not 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.
