Customer self-repair parts
Customer Self-Repair (CSR) parts are available for many HP LaserJet printers to reduce repair time.
More information about the CSR program and benefits can be found at
http://www.hp.com/go/csr-support and http://www.hp.com/go/csr-faq.
Genuine HP replacement parts can be ordered at http://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.

Introduction
Use HP Cartridge Policy and Cartridge Protection to control which cartridges are installed in the printer
and protect the cartridges that are installed from theft.
● Cartridge Policy: This feature protects the printer from counterfeit toner cartridges by allowing
only genuine HP cartridges to be used with the printer. Using genuine HP cartridges ensures the
best possible print quality. When someone installs a cartridge that is not a genuine HP cartridge,
the printer control panel displays a message that the cartridge is unauthorized and it provides
information explaining how to proceed.
● Cartridge Protection: This feature permanently associates toner cartridges with a specific printer,
or fleet of printers, so they cannot be used in other printers. Protecting cartridges protects your
investment. When this feature is enabled, if someone attempts to transfer a protected cartridge
from the original printer into an unauthorized printer, that printer will not print with the protected
cartridge. The printer control panel displays a message that the cartridge is protected, and it
provides information explaining how to proceed.
CAUTION: After enabling cartridge protection for the printer, all subsequent toner cartridges
installed in the printer are automatically and
permanently
protected. To avoid protecting a new
cartridge, disable the feature
before
installing the new cartridge.
Turning the feature off does not turn off protection for cartridges that are currently installed.
