z Secure initialize
When initializing the data in the scanner, the free disk space can be also
overwritten with meaningless random data. When the user data store is cleared
from the scanner, the old cipher key is deleted and a new cipher key is generated.
This totally eliminates the possibility of access to any user data remaining in the
free disk space.
There is no input pathway to the scanner for files via external memory media, and input
pathways of files via the network are limited to the minimum. Security patches are
provided to protect the scanner against virus attacks. Taking these measures enables the
scanner to be protected against virus infection.
