In “setting for HDD overwriting function for residual data,” the number of overwriting and erasing used

document data recorded on the hard disk drive can be set to one of those described below:

- Not perform: Does not overwrite nor erase.

Set when security functions of TOE are not used. Lowering of process speed of

copy and printer functions, which occurs due to overwriting and erasing, can be

avoided.

- Perform

(one time): Overwrites and erases with data “0” once.

Overwriting and erasing makes the recovery of used document data difficult.

Has less effect of lowering process speed of copying and printing than

three-time overwritings and erasings. Protects used document data by being set

in combination with the setting for HDD data encryption function.

- Perform

(three times): Overwrites and erases with data “random numbers” twice, and with data “0”

once. Recommended setting value. Although the recovery of used document

data is difficult after one-time overwriting and erasing, three-time overwritings

and erasings make the recovery more difficult. Protects used document data by

being set in combination with the setting for HDD data encryption function.

“Setting for using password” can be set to either of those described below:

- Not perform: Does not use password.

In authentication of key operator, requests entering of only the user ID of key

operator and authenticates him or her as a key operator when the entered user

ID matches the information recorded on NVRAM of MFP. Used when

convenience is desired, although the security level is low.

- Perform: Uses password.

In authentication of key operator, requests entering of user ID and

password of key operator and authenticates him or her as a key operator when

the entered user ID and password match the information

recorded on NVRAM of MFP.

In “setting for HDD data encryption function,” cryptographic operation on document data stored on

the hard disk drive can be set to either of those described below:

- Not perform: Does not encrypt.

Set when security functions of TOE are not used. Lowering of process speed
