By adding barcode which indicates JOB number on each document, the DC-646 automatically sets
up the machine and starts the JOB. An operator can press the START key and leave.
Even if multiple types of JOBs are loaded on the feed tray at one time, the DC-646 recognizes
barcode on documents also with the built-in CCD scanner and automatically switches setup and
fi
nishes the JOBs.
To use this function, each document must have barcode printed on it. Please refer to the following
instructions for speci
