Erase All Memory
You can erase all the data on the hard disk by writing over it. This is useful if you relocate or dispose of
your machine. The amount of time it takes to completely erase the memory depends on the machine type
being used. For information on machine types, see "Machine Types", Read This First.
• If you select "Erase All Memory", the following are also deleted: user codes, counters under each
user code, user stamps, data stored in the Address Book, printer fonts downloaded by users,
applications using Embedded Software Architecture, SSL server certificates, and the machine's
network settings.
•
If the main power switch is turned off before "Erase All Memory" 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 SmartDeviceMonitor for Admin to
back up the user codes, the counters for each user code, and the Address Book. The Address Book
can also be backed up using Web Image Monitor. For details, see SmartDeviceMonitor for Admin
Help or Web Image Monitor Help.
• Other than pausing, no operations are possible during the "Erase All Memory" process. When
"Random Numbers" is selected and it is set to overwrite three times, types 1 and 2 take a maximum
of 3 hours, 45 minutes and types 3 and 4 take a maximum of 4 hours and 15 minutes.
• The "Erase All Memory" function also clears the machine's security settings, with the result that
afterward, neither machine nor user administration will be effective. Ensure that users do not save
any data on the machine after "Erase All Memory" has completed.
Using Erase All Memory
1. Disconnect communication cables connected to the machine.
2. The machine administrator logs in from the control panel.
3. Press [System Settings].
4. Press [Administrator Tools].
