Security
Confidential information is always at risk of being copied without permission or
subject to unauthorized access through the network. To protect documents from
these types of risks, not only can passwords be set, but also the Extended Secu-
rity function can be used to strengthen security.
For those who require ample document protection, we recommend that the Ex-
tended Security function be used.

By setting a password, operations with documents such as printing, deleting, or
delivering can be restricted to authorized users and access denied to others.
However, a password is breakable. When the Extended Security function is
used, entering the wrong password 10 times will lock a document, protecting it
from illegitimate accesses.
For unlocking documents, see p.150 “Unlocking a Locked Document”.
The documents that can be protected by the Extended Security function are as
follows. All documents must be set with a password to be protected by this func-
tion.
