When scanning originals using the ADF, a TX Stamp is printed on a scanned original to certify that the original has been scanned. It is used when sending a fax.
To use this function, the optional Stamp Unit is required.
The ink used for stamping is consumables. If the ink becomes faint, contact your service representative.
If [Mixed Original] is specified to scan originals, TX Stamp may not be printed on the specified position.
