EN Changing Settings in the Printer Control Panel 49
Locking the Printer Control Panel
You can prevent users from changing the printer control panel
settings by establishing a password, thus enabling the printer control
panel lock. When locked, unauthorized users who try to change
settings in the printer control panel will receive an
ACCESS DENIED
message.
If you are using Microsoft Windows, use either the HP Web JetAdmin
software or a PJL Command. The easier of the two methods is
through the HP Web JetAdmin software. For more information on
using the HP Web JetAdmin software to perform this function, see the
HP Web JetAdmin online help.
If you are using Mac OS, use the HP LaserJet utility. From the
HP LaserJet utility, on the Security tab select Lock Control Panel.
Note If you have forgotten the password for the printer control panel, print
a configuration page, an EIO page, and a menu map page, then reset
the printer with a cold reset. To perform a cold reset, turn the printer
off then hold down the green
G O button and turn the printer on. When
the front panel displays COLD RESET , release the green G O button. All
printer settings (including internal print server card settings) will
return to the factory defaults, all passwords will be cleared, and the
printer control panel will be unlocked. Use the pages listed above to
restore the printer settings. For more information on printing these
pages, see “
Printing Internal Pages ” later in this chapter.
