If [Simple Encryption] is specified, all jobs that pass user authentication are accepted.
If [DES] is specified, jobs encrypted with DES or AES are accepted.
If [AES] is specified, jobs encrypted with AES are accepted.
If you select [AES] or [DES], specify the encryption settings using the printer driver. For details
about specifying the printer driver, see the printer driver Help.
Default: [Simple Encryption]
Restrict Display of User Information
This can be specified by the machine administrator.
This can be specified if user authentication is specified. When the job history is checked using a
network connection for which authentication is not available, all personal information can be
displayed as "********". For example, when someone not authenticated as an administrator
checks the job history using SNMP in SmartDeviceMonitor for Admin/Device Manager NX Lite,
personal information can be displayed as "********" so that users cannot be identified. Because
information identifying registered users cannot be viewed, unauthorized users are prevented from
obtaining information about the registered files.
Default: [Off]
Encrypt User Custom Settings & Address Book
This can be specified by the user administrator.
Encrypt the individual settings of the machine's users and the data in the Address Book.
Even if information on an internal part has been leaked, encryption prevents the individual user
settings or the Address Book data from being read.
For details, see page 93 "Protecting the Address Book".
Default: [Off]
Enhance File Protection
This can be specified by the file administrator.
By specifying a password, you can limit operations such as printing, deleting, and sending files,
and can prevent unauthorized people from accessing the files. However, it is still possible for the
password to be cracked.
By specifying "Enhance File Protection", files are locked and so become inaccessible if an invalid
password is entered ten times. This can protect the files from unauthorized access attempts in which
a password is repeatedly guessed.
When "Enhance File Protection" is specified, ( ) appears in the lower right corner of the screen.
The locked files can only be unlocked by the file administrator.
When files are locked, you cannot select them even if the correct password is entered.
Default: [Off]
