To specify the driver encryption key, register the encryption key specified using the printer in the
driver.
For details, see page 153 "Specifying a Driver Encryption Key".
Encrypt Address Book / Encrypt User Custom Setting & Address Book
This can be specified by the user administrator.
If you are using SP 4510DN, encrypt the data in the printer's Address Book.
If you are using SP 4520DN, 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, the encryption prevents the Address Book
data from being read.
For details, see page 81 "Protecting the Address Book".
Default: [Off]
Restrict User Info.Display / 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, 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]
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.
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]
Settings by SNMPv1 and v2
This can be specified by the network administrator.
