Memory Transmission and Parallel Memory Transmission
The base copier's scanner scans the original at the selected resolution in inch
format. The BiCU processes the data and transfers it to the FCU.
NOTE: When scanning a fax original, the BiCU uses the MTF and thresholding
parameter settings programmed in the fax unit’s scanner bit switches,
not the copier's SP modes.
Then, the FCU converts the data to mm format, and compresses the data in MMR
or raw format to store it in the SAF memory. If image rotation is possible, the image
is rotated in page memory before compression.
At the time of transmission, the FCU decompresses the stored data, then re-
compresses and/or reduces the data if necessary for transmission. The NCU
transmits the data to the line.
Immediate Transmission
The base copier's scanner scans the original at the resolution agreed with the
receiving terminal. The BiCU video processes the data and transfers it to the FCU.
NOTE: When scanning a fax original, the BiCU uses the MTF 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.
