Encrypting Data on the Hard Disk
Encrypt data stored on the hard disk to prevent information leakage. To encrypt the stored data, the
hard disk and the SD card supplied with the hard disk are required. For details, see p.63 "Encrypting
Data on the Hard Disk".
Overwriting the Data on the Hard Disk
Before disposing of the printer, make sure all data on the hard disk is deleted. Prevent data leakage
by automatically deleting transmitted printer jobs from the memory.
To overwrite the hard disk data, the hard disk and the SD card supplied with the hard disk are required.
For details, see p.68 "Deleting Data on the Hard Disk".
Limiting and Controlling Access
Preventing Changes to Printer Settings
The printer settings that can be modified depend on the type of administrator account.
Register the administrators so that users cannot change the administrator settings. For details about
Preventing Changes to Printer Settings, see p.73 "Preventing Changes to Printer Settings".
Limiting Available Functions
To prevent unauthorized operation, you can specify who is allowed to access each of the printer's
functions. For details about limiting available functions for users and groups, see p.75 "Limiting
Available Functions".
Enhanced Network Security
Preventing Unauthorized Access
You can limit IP addresses or disable ports to prevent unauthorized access over the network and
protect the Address Book, stored files, and default settings. For details about preventing unauthorized
access, see p.81 "Preventing Unauthorized Access".
Encrypting Transmitted Passwords
We recommend you use one or more of the following security protocols: IPsec, SNMPv3, and SSL.
Using these protocols can enhance your printer's security to make login and IPP authentication
passwords harder to break.
Also, encrypt the login password for administrator authentication and user authentication. For details
about encrypting transmitted passwords, see p.92 "Encrypting Transmitted Passwords".
Safer Communication Using SSL, SNMPv3 and IPsec
You can encrypt this printer's transmissions using SSL, SNMPv3, and IPsec. By encrypting transmitted
data and safeguarding the transmission route, you can prevent sent data from being intercepted,
