Document Scan Lock - Canon imageRUNNER ADVANCE 4051/4045/4035/4025 e-Manual

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 canceled, 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] 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 copy (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:

Original with Embedded TL Code (Scan Lock Information)		Copying/Sending/Storing/Printing are restricted.

Tracking Information

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 canceled: 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).

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 canceled:

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).

IMPORTANT
The Document Scan Lock mode does not guarantee restriction of unauthorized copying. You may not be able to restrict unauthorized copying or analyze tracking information, depending on the combination of settings and the output such as a document with an image on the entire page.
