Deleting Data on the Hard Disk
This can be specified by the machine administrator.
To use this function, the optional DataOverwriteSecurity Unit must be installed.
The machine's hard disk stores all document data from the copier function. It also stores the data of users'
document boxes and code counters, and the Address Book.
Auto Erase Memory
A document scanned in copier is temporarily stored on the machine's hard disk. Even after the job is
completed, it remains in the hard disk as temporary data. Auto Erase Memory erases the temporary data
on the hard disk by writing over it.
Overwriting starts automatically once the job is completed.
The copier function take priority over the Auto Erase Memory function. If a copy job is in progress,
overwriting will only be done after the job is completed.
Overwrite Icon
If this option has been correctly installed and is functioning properly, the Data Overwrite icon will be
indicated in the bottom right hand corner of the panel display of your machine when Auto Erase Memory
is set to [On].
Dirty
This icon is lit when there is temporary data to be overwritten, and
blinks during overwriting.
Clear This icon is lit when there is no temporary data to be overwritten.
