2. Redundancy Compression Process Coding Mode
This unit uses one-dimensional MH format.
Signal
Identification Signal Format Function
Image Signal
Sends 12 bits (0...01 • ~ 6 times) to the receiver at the
same speed as the image signal and notifies completion
of the first sheet.
RTC
(Return to Control)
End of one communication
EOP
(End of Procedure)
MCF
(Message Confirmation)
DCN
(Disconnect)
End of 1 page reception
Phase E starts.
Completion of transmission of 1 page. If there are still
more documents to be sent, they are output instead of
EOP. After MCF reception, the sender transmits an
image signal of the second sheet.
If there is an operator call from the sender, it is output
after RTC.
This is output when an operator call is received.
MPS
(Multi-Page Signal)
