Chapter 4 HP LaserJet and Color LaserJet MFP Security Checklist 42
Configuring Security Settings
The Security category includes many advanced security settings and password settings. If you
are attempting to configure a setting that is in the Security category and not listed in this section,
you should check the chapter on Advanced Security for multiple MFPs. To set the basic required
settings in this category follow the steps in the sections below.
Bootloader Password
The Bootloader password protects features, such as the MFP reset options that are available on the
MFP control panel. These features are not commonly known, but they can severely affect the MFPs
if they are executed improperly. The Bootloader password is not configured by default.
CAUTION:
Be very careful to remember the bootloader password that you provide.
Once you configure the bootloader password, the bootloader features
will be inaccessible permanently without it. The only way to restore the
default setting and clear the password is to provide the correct
password and set it with a blank password.
On the Config tab under the Security category page, select the Bootloader
Password option (Figure 39)
Figure 39: The Bootloader Password option.
Type a password of 9 to 16 numeric digits in the New Password field, and repeat it
exactly in the Repeat Password field.
Note:
To reset (clear) this password, click to select Bootloader Password, type
the correct current password, and leave the New Password and Repeat
Password fields blank. Then click Configure, and the bootloader
password will be cleared in the MFPs.
