The TOE verifies the role for an authorised TOE user who attempts to start operating Copy Function, Printer
Function, Scanner Function, Document Server Function, and Fax Function.
If the role is that of normal user, the user can operate only functions that are included in the available
function list set for each normal user.
If the role is that of MFP administrator, the user can operate Fax Reception Function that corresponds to
MFP management.
If the role is that of supervisor and RC Gate, using any functions is not allowed.

7.6 Residual Data Overwrite Function
The Residual Data Overwrite Function is to overwrite specific patterns on the HDD and disable the reusing
of the residual data included in the deleted documents, temporary documents and their fragments on the
HDD.
FDP_RIP.1
Methods to delete the HDD area through overwriting include sequential overwriting and batch overwriting.
For sequential overwriting, the TOE constantly monitors the information on a residual data area, and
overwrites the area if any existing residual data is discovered. If the user deletes document data, the TOE
