TSI Print (Transmitting Subscriber Identification Print)

You can have the sender's Own Name or Own Fax Number printed on documents that this machine receives.

Usually the sender's Fax Header is printed on received documents. If the sender has not programmed their Fax Header, you will not be able to identify them. However, if you turn this function on, the sender's Own Name or Own Fax Number is printed instead so you can find out where the document came from.
