NOTE: The Windows software installer installs the HP Smart Device Agent Base service. The le size is less
than 100 kb. Its only function is to check for printers connected via USB hourly. No data is collected. If a USB
printer is found, it then tries to locate a JetAdvantage Management Connector (JAMc) instance on the network. If
a JAMc is found, the HP Smart Device Agent Base is securely upgraded to a full Smart Device Agent from JAMc,
which will then allow printed pages to be accounted for in a Managed Print Services (MPS) account. The driveronly web packs downloaded from www.hp.com for the printer and installed through the Add Printer wizard do
not install this service.

●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 benets 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
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.

Dynamic security
Learn about dynamic-security-enabled printers.
Certain HP printers use cartridges that have security chips or electronic circuitry. Cartridges using a non-HP chip
or modied or non-HP circuitry* might not work. And, those that work today might not work in the future.
As is standard in the printing business, HP has a process for authenticating cartridges. HP continues to use
security measures to protect the quality of our customer experience, maintain the integrity of our printing
systems, and protect our intellectual property. These measures include authentication methods that change
periodically and might prevent some third-party supplies from working now or in the future. HP printers and
original HP cartridges deliver the best quality, security and reliability. When cartridges are cloned or
counterfeited, the customer is exposed to quality and potential security risks, compromising the printing
experience.
*Non-HP Chips and modied or non-HP electronic circuitry are not produced or validated by HP. HP cannot
guarantee that these chips or circuitry will work in your printer now or in the future. If you are using a nonoriginal HP cartridge, please check with your supplier to ensure your cartridge has an original HP security chip or
unmodied HP electronic circuitry.

Introduction

Enable or disable the Cartridge Protection feature
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.
In HP Web Jetadmin, the settings are located under the Device Management pane in the following menu chain:
Cong > Supplies > Cartridge Policy or Cartridge Protection.
These features are available with HP FutureSmart versions 3 and later. Both features are o by default.
●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 specic printer, or eet 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 o does not turn o protection for cartridges that are currently installed.
