Erasing data when the machine is to be discarded or use of a leased machine is terminated

2.10 Erasing data when the machine is to be discarded or use of a
leased machine is terminated
When access to the machine by the Administrator of the machine through the Administrator Settings from
the control panel is authenticated, the machine enables setting of the operations of the Overwrite All Data
and Restore All functions.
When the machine is to be discarded or use of a leased machine is terminated at the end of the leasing con-
tract, be sure to erase all data to prevent data left in the machine from leaking. Different methods of erase
apply depending on the data space. See the table below for more details.
Data space
HDD, Memory area on the MFP board
Memory area on the MFP board
NOTICE
Perform erase operations for all of HDD and memory area on the MFP board.
When erase operations are performed, make sure that the operation is normally terminated for data in each
of the three different data spaces. If an error occurs during execution of the erase operations, contact your
Service Representative for appropriate action.
The Enhanced Security Mode is set to [OFF], if Overwrite All Data or Restore All is executed.
The encryption key is registered in the memory area on the MFP board, but is not deleted even if Restore All
or Overwrite All Data is performed. After Restore All or Overwrite All Data is performed, the encryption key
must be deleted manually. For details, see page 2-24.
