Checking the Destination Machine’s Number Before Transmission
ID check transmission limits fax transmission to when the lower four digits of the fax
number you dialed and those registered in the destination machine match. Transmission
is allowed only when the passcodes are matched.
Note
If a fax number is not registered for the destination, a communication error occurs
•
and transmission fails.
You can also set to always enable ID check transmission. For details, refer to
•
Chapter 2, “Setting ID Check Transmission” in the Administrator’s Guide.
When using manual transmission (transmission using an optional handset, an
•
external phone handset or the [Monitor] function), the ID check transmission
function is disabled, even if you set it to ON.
