15 Tools Overwrite Hard Disk Select whether or not to conduct hard disk overwriting. If you overwrite the hard disk, you can select whether to overwrite once or three times. When copy, fax, scan, or print processing is completed, the data is deleted from the hard disk and the area on which the deleted data was stored is automatically overwritten with blank data. This feature prevents unauthorized retrieval or restoration of the data recorded on the hard disk. It also applies to copy document and other information stored temporarily by the system. The following option can be configured. Number of Overwrites You can select the number of overwrites either once or three times. Note • If the machine is turned off during the overwriting, unfinished files may remain on the hard disk. The overwriting will resume if you turn the machine on again with the unfinished files remaining on the hard disk. • Overwriting once erases the data, but overwriting three times makes it even more definite that the data cannot be restored. It does, however, take longer. • During overwriting, normal operations may be slowed down. For more information on how to check the status during overwriting, refer to "Overwrite Hard Disk" (P.285). 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. For more information on how to set data encryption, refer to "Data Encryption" (P.344). For more information on how to set service representative restricted operation, refer to "Service Rep. Restricted Operation" (P.346). For more information on how to set [Passcode Entry for Control Panel Login], refer to "Passcode Policy" (P.456). For more information on how to set the system administrator's user ID, refer to "System Administrator's Login ID" (P.450). The manager (of the organization that this machine is used for) must follow the instructions below: • Assign an appropriate person as a system administrator and manage and train he/she properly. 460
