Data Security for Copying
Using the printer driver to enable data security for the copying function, you can
print a document with an embedded pattern of hidden text. Such a document is
called a data security for copying document.
If a data security for copying document is copied or stored in the Document
Server using a copier or multi-function printer with the Copy Data Security Unit,
protected pages are grayed out in the copy, preventing confidential information
being copied. Also if a document with embedded pattern is detected, the ma-
chine beeps. The unauthorized copy log is also stored. To gray out copies of data
security for copying documents when they are copied or stored in the Document
Server, the optional Copy Data Security Unit must be installed in the machine.
1. Documents with data security for
copying
2. The document is copied or stored
in the Document Server.
3. Printed Copies
Text and images in the document are
grayed out in printed copies.
Limitation
❒ If the Copy Data Security Unit is installed in the machine, you cannot use the
scanner and fax functions.
❒ If the Copy Data Security Unit is installed, you cannot specify a scaling factor
less than 50% using the Control Panel under the Copier and Document Server
functions.
❒
If a document with embedded pattern for data security for copying is copied,
or stored in the Document Server by a copier or multi-function printer without
Copy Data Security Unit, the embedded pattern appears conspicuously in the
copy. However, how conspicuously the text appears depends on the model of
the copier or multi-function printer being used and its scanning setting.
