JBIG Transmission
If you use JBIG (Joint Bi-level Image experts Group) compression, you can send originals scanned using [Photo] faster than with other compression methods.
This function is not available for Internet Fax.
This function requires that the other party's fax machine has both the JBIG function and ECM function.
If ECM is turned off, JBIG transmission is unavailable.
