1.4.3 PC FAX COMMUNICATION
Direct transmission
IBM Compatible
The host computer sends commands and image data to the machine through the
DIU during transmission.
NOTE: 1) Group dials programmed in the machine cannot be used.
2) T.30 optional protocols (e.g., BFT) are not supported by class 2 fax
communication.
3) ISDN G4 numbers programmed in quick or speed dials cannot be used.
(Only for Europe model)
4) If ISDN is selected for G3 communication (system switch 0A, bit 6), the
G3 numbers must have been programmed in quick or speed dial.
(Only for Europe model)
Memory transmission
IBM Compatible
The host computer sends destination number(s) and image data to the machine
through the DIU during transmission. The machine stores the image in the SAF
memory, then makes a fax transmission.
NOTE: 1) If the memory overflows while storing the first page into SAF memory,
the machine does not start the transmission.
2) If the memory overflows while storing the second or subsequent page
into SAF memory, the machine transmits all the successfully stored
pages.
3) When fax numbers programmed in the machine's quick or speed dials
are specified using the PC fax application, all the specified numbers
must have been programmed in the fax machine.
4) T.30 optional protocols (e.g., BFT) are not supported by class 2 fax
communication.
