If the Data Overwrite icon continues to be "Dirty" when there is no data to be overwritten,
turn off the main power of the machine. Turn it back on and see if the icon changes to
"Clear". If it does not, contact your sales or service representative.
Overwrite and erase all data stored on the hard disk when you relocate or dispose of the machine. The
device settings stored on the machine's memory are initialized.
For details about using the machine after executing Erase All Memory, contact your service
representative.
If your machine is equipped with the Enhanced Security HDD Option, the hard disk automatically
discards the encryption key, making it impossible to decrypt the data on the hard disk before the
data is erased using the selected overwriting method.
If the main power switch is turned off before the Erase All Memory process is completed,
overwriting will be stopped and data will be left on the hard disk.
Do not stop the overwrite mid-process. Doing so will damage the hard disk.
We recommend that before you erase the hard disk, you use Device Manager NX to back up the
user codes, the counters for each user code, and Address Book. For details, see Device Manager
NX Help.
If the method of Random Numbers is selected and overwrite three times is set, the Erase All
Memory process takes up to 2 hours and 51 minutes. You cannot operate the machine during
overwriting.
The Erase All Memory function also clears the machine's security settings, so that neither
machine nor user administration will be possible. Ensure that users do not save any data on the
machine after the Erase All Memory process is completed.
When the extended features are installed on the machine, uninstall them before executing Erase
All Memory. For details about uninstalling the extended features, see Extended Features Settings.
