Document Scan Lock

You can embed hidden information (TL code*1) on the output to restrict unauthorized copying. You can also embed information, such as the user name, date, and device name, so that you can find out who, when, and with which machine the copy was made.
For information on the optional products required to use this function, see "Optional Products Required for Each Function."
If you set a mode*2 that affects the TL code when attempting to copy, scan, or print a document with embedded information, that job is cancelled, and the message <The job was stopped because embedded information was detected.> is displayed on the touch panel display.
To restrict and gray out functions that affect the TL code, set [Restrict Options] in [Function Settings] (Settings/Registration) to 'On'.(See "Specifying the Document Scan Lock Operational Settings.")
*1 A TL code is a type of 2-dimensional bar code. A TL code is printed and by changing the arrangement of the dots, digital information is embedded on the output.
*2 This refers to modes such as the cascade copy mode and the zoom ratio, page layout, booklet, density, page numbering, and copy set numbering modes, that set reduction/enlargement, and printing and density changes.
The following three types of information can be used with this mode:
Scan Lock Information

Make sure to use the correct paper size and type to effectively use the Scan Lock Information and Tracking Information. (See "Available Paper Stock.")

Scan Lock Information

You can embed TL code on the output to restrict unauthorized copying. You can select the following four types of restriction.
Allow All
The output can be copied.
Prohibit All
Copying of outputs is restricted. You cannot copy an output for which Prohibit All is detected.
Password Authentication
Copying of outputs is restricted. You can copy only if the authentication process is successful.
User Authentication
Copying of outputs is restricted. You can set User Authentication restriction if the Department ID Management or authentication by SSO-H is set. You can copy only if the Department ID or user name matches.
NOTE
When copying documents set with [Password Auth.] or [User Authentication], the embedded information on the first page is used for authentication. In the following case, the job will be cancelled:
When the embedded information on the first page differs from the embedded information on the second and subsequent pages (for example, when copying a document with the password '1234567' embedded on the first page, and the password '9876543' embedded on the second page).
