Thus, configuring security features and passwords and updating them regularly for - HP FM892UT#ABA | HP LaserJet MFP and Color MFP Products - Configuring Security f - Page 50
passwords can eliminate access to an MFP. Be careful to record them in a safe place. It is most important to remember the Bootloader password. With it, it is possible to restore the MFPs to factory default settings. Without it, the only way to restore the MFPs is to involve an HP-authorized service - HP FM892UT#ABA | HP LaserJet MFP and Color MFP Products - Configuring Security f - Page 51

this password. Without the password, the MFP denies access to the File System and to File System configurations. Web Jetadmin stores the file system password in its encrypted device cache. It automatically provides the password when the MFPs request it.

. • Disable FTP Printing. FTP Printing enables some methods of upgrading MFP firmware, and it allows for uploading files onto MFP hard drives. HP recommends disabling it and using Web Jetadmin to upgrade firmware. MFPs will deny access to FTP sessions. • Disable LPD Printing. LPD Printing is the - HP FM892UT#ABA | HP LaserJet MFP and Color MFP Products - Configuring Security f - Page 63

Web browsers that do not support SSL and high encryption strength will not be able to access the MFP EWSs. This checklist recommends - HP FM892UT#ABA | HP LaserJet MFP and Color MFP Products - Configuring Security f - Page 64
deny access to users who cannot supply the correct credentials. • Disable Printer Firmware Update. Printer Firmware Update enables the MFPs to accept printer firmware updates from various sources. Disabling it ensures that no one can send firmware updates to the MFPs. HP recommends updating firmware - HP FM892UT#ABA | HP LaserJet MFP and Color MFP Products - Configuring Security f - Page 65
restricts this access to PCL and PostScript commands. With the PJL Password configured, the MFPs will deny access to commands that attempt to change default settings without the correct password. • Configure color restriction settings. If your network includes Color LaserJet MFPs, you can configure - HP FM892UT#ABA | HP LaserJet MFP and Color MFP Products - Configuring Security f - Page 66
• No way to change the From Address on email send jobs: Depending on the capabilities of your network, the MFPs will place either a default from address or the user's email address as the From Address.
