VIDEO DATA PATH

4.3.1 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, 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 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 will be done, 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.
