2.2 CLASS 2 FAX COMMUNICATION
2.2.1 DIRECT TRANSMISSION
SAF
DCR
IBM Compatible
FCU
ModemDIU
NCU
A824D001.WMF
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) ISDN G4 numbers programmed in quick or speed dials cannot be used.
3) If ISDN is selected for G3 communication (system switch 0A, bit 6), the
G3 numbers must have been programmed in quick or speed dial.
4) T.30 optional protocols (e.g., BFT) are not supported by class 2 fax
communication.
2.2.2 MEMORY TRANSMISSION
SAF
FCU
DCR
ModemDIU
IBM Compatible
NCU
A824D002.WMF
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.

2.2.3 DIRECT RECEPTION
SAF
DCR
IBM Compatible
FCU
ModemDIU
NCU
A824D003.WMF
The machine transfers received image data directly to the host PC without storing it
into SAF memory.
NOTE:
1) If the host PC is not ready to receive a fax message, the machine
receives the message into SAF memory.
2) Even if the SAF memory is full, the machine starts fax reception.
However, the machine will not continue reception if the host computer is
not ready to receive a message.
3) The “Number of rings to answer” parameter in the PC fax application
must not exceed 4.
2.2.4 MEMORY RECEPTION
SAF
DCR
IBM Compatible
FCU
ModemDIU
NCU
A824D004.WMF
The machine receives a fax message in the SAF memory, then transfers data to
the host computer after the reception has finished. The machine prints the received
message after transferring data to the host if user parameter 20 – bit 4 is set to “1:
Print”.
NOTE:
1) If an error occurs due to cable disconnection, the PC fax application
must be restarted to receive the message.
2) Memory reception is not possible when forwarding is enabled.
3) Manual reception from the PC fax application is not supported.
4) The “Number of rings to answer” parameter in the PC fax application
must not exceed 4.

A824D006.WMF
The machine receives print data into SAF memory as fax image data, then prints it
after all the data has been transferred from the host PC.
The destination number “0000” informed from the host PC identifies a print job.
NOTE:
1) If SAF memory runs out while receiving print data, the machine prints up
to the successfully received data.
2) The machine cannot receive print data while printing a message from
the SAF memory. The data will be received after printing.
3) If a fax destination is specified together with the print destination “0000”,
the destinations specified after “0000” will be delayed until the machine
prints all pages in the message.

THIS OPTION MUST BE INSTALLED BY A CUSTOMER SERVICE REPRESENTATIVE
WHO HAS COMPLETED THE TRAINING COURSES FOR THE BASE COPIER AND
THIS OPTION.
NOTE:
I
Before installing this option, turn off the main switch, and disconnect the
power cord.
1) Never install telephone wiring during a lightning storm.
2) Never install telephone jacks in wet locations unless the jack is
specifically designed for wet locations.
3) Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
4) Use caution when installing or modifying telephone lines.
5) Avoid using a telephone (other than a cordless type) during an electric
storm. There may be a remote risk of electric shock from lightning.
6) Do not use an telephone to report a gas leak in the vicinity of the leak.
