Unauthorized Copy Prevention
Using the printer driver, you can embed mask and pattern (for instance, a warning such as "No Copying")
in the printed document.
If the document is copied, faxed or scanned by a copier or multifunction printer, the embedded pattern
appears clearly on the copy, discouraging unauthorized copying.
To use the printer function when User Authentication is enabled, you must enter the login user name and
password for the printer driver. For details, see the printer driver Help.
• Unauthorized copy prevention discourages unauthorized copying, but will not necessarily stop
information leaks.
• The embedded pattern cannot be guaranteed to be copied, faxed or scanned properly.
• Depending on the machine and scanner settings, the embedded pattern may not be copied, scanned
or faxed.
1. Printed Documents
Using the printer driver, you can embed background images and pattern in a printed document for Unauthorized
Copy Prevention.
2. The document is copied, faxed or scanned.
3. Printed Copies
The embedded pattern (for instance, a warning such as "No Copying") in a printed document appears clearly
in printed copies.
• To make the embedded pattern clear, set the character size to at least 50 pt (preferably 70 to 80 pt)
and character angle to between 30 and 40 degrees.
