Immediate Transmission
The base copier's scanner scans the original at the resolution agreed with the receiving terminal.
The IPU video processes the data and transfers it to the FCU.
 When scanning a fax original, the IPU uses the MTF, independent dot erase and
thresholding parameter settings programmed in the fax unit’s scanner bit switches, not
the copier's SP modes.
Then the FCU stores the data in page memory, and compresses the data for transmission. The
NCU transmits the data to the line.
JBIG Transmission
Memory transmission: If the receiver has JBIG compression, the data goes from the DCR to the
QM-Coder. Then the NCU transmits the data to the line. When an optional G3 unit (SG3) is
installed and PSTN2 is selected as the line type, JBIG compression is available, but only for the
PSTN-2 line.
