Locking the control panel You can prevent users from changing printer control panel settings by establishing a password and locking the printer control panel. The control panel offers multiple levels of security. You can lock certain control panel menus, allowing users to change the rest of the menus, or you can lock all of the menus-and you can even lock the [CANCEL JOB] key. When the printer control panel is locked, unauthorized users who try to change settings at the control panel receive the following message: ACCESS DENIED MENUS LOCKED Levels of security Table 3-1 Printer security levels Lock setting Control panel items locked 0 = None No items are locked 1 = Minimum Configuration Menu I/O Menu Calibration Menu Resets Menu 2 = Moderate Configuration Menu I/O Menu Calibration Menu Resets Menu Paper Handling Menu 3 = Maximum Configuration Menu I/O Menu Calibration Menu Resets Menu Paper Handling Menu Information Menu Printing Menu [CANCEL JOB] key Use HP JetAdmin software, HP LaserJet Utility for Macintosh, or an ASCII escape sequence to perform this procedure. HP software, which comes on the software CD-ROM, is easier to use than an ASCII escape sequence. For instructions about locking the control panel by using either HP JetAdmin software or the HP LaserJet Utility for Macintosh, go to the online Help for that software. 74 Installation and configuration C7085-90921
