Encryption Function
The printer temporarily stores print jobs on an internal hard disk. If the hard
disk is stolen, there is a risk that the data might be passed to unauthorized
parties or modified.
The Security Kit encrypts data before storing data on the hard disk. The
stored data cannot be decrypted by other than normal printing or
operations, higher security is provided in case the hard disk is stolen.
Since the encryption is performed automatically, no special operation is
required.
IMPORTANT: Although the encryption function strengthens data security,
data stored in the virtual mailbox can be decrypted by normal print
operations. Therefore do not store data that must not be leaked on the
virtual mailbox.
