Front-panel security settings
From the front panel, you can tap , then Security, to control some of the features of the printer:
●
User sessions: Enable or disable automatic log-out after 1, 3, or 5 minutes.
● Embedded Web Server: Enable or disable the Embedded Web Server.
● Printing & management Web services: Enable or disable Web services that are used by printing and
management tools such as the HP Utility, HP Click, and SDK for RIPs.
If an administrator password has been set, it must be given in order to perform the following operations:
● Change the security settings (including the administrator password itself)
● Change the conguration of the Internet connection
● Change the Automatic Firmware Update conguration
● Enable or disable automatic downloading and/or installation of automatic rmware updates
● Restore an earlier rmware version
● Reset factory defaults
NOTE: The administrator password can contain only characters that appear on the front panel's on-screen
keyboard. If you set a new password with the Embedded Web Server, it will reject characters that do not appear
in that limited character set.
Require account ID
If you want to keep records of printer usage by dierent users, you can set your printer to require an account ID
for each job. At the front panel, tap , then Job management > Job queue > Account ID.
If this setting is turned on, the account ID eld will be mandatory and jobs with no account ID will be kept "on hold
for accounting".
The account ID can be set in the printer driver when sending the job. If the job is set "on hold for accounting" by
the printer, you can introduce the account ID in the driver or front panel, by going to the job queue and clicking
the job that is on hold. A window with a text box is displayed and you can enter the account ID into it.
