Prerequisite for Using Data Security Feature
The system administrator must follow the instructions below:
• To protect the data deleted from or stored on the hard disk, the following settings are
required:
- Number of Overwrites: [1 Overwrite] or [3 Overwrites]
- Data Encryption: [On]: an encryption key of 12 digits
- Service Representative Restricted Operation: [Yes]
• Change the system administrator's factory default passcode (1111). Register a new
passcode of 7 characters or more (maximum 12 characters). Be careful not to register a
passcode that can be easily assumed and not to store the registered passcode on a location
that is easily accessible to other persons.
Note • If the system administrator's user ID and passcode are forgotten, the machine configuration will not
be able to recover in case of malfunction.
• Set [Passcode Entry for Control Panel Login] to [On].
• Set [Maximum Login Attempts by System Administrator] to 5 times.
• Note that the hard disk security will not be warranted if you do not correctly follow the
above setting instructions.

off the machine after an active operation completes, if any.

perform the network settings properly to protect the machine from interceptions.
• To block unauthorized access, install a firewall device between the external network and
the internal network that the machine is located on.

- Do not use easily assured character string
- Use both characters and numerics
