No additional notes.
The ARDF uses an FRR (feed & reverse roller) system.
The DF-Feed Motor drives the DF pickup roller, DF feed
roller, DF separation roller, and transport roller.
The pickup roller drives the top sheet(s) between the
feed and separation roller, where the top sheet is
separated and fed to the transport rollers.
The DF feed clutch stops feeding when the original is fed
to the inverter tray in double-sided mode. If the DF feed
clutch didn't stop pick-up, feed, and separation rollers in
double-sided mode, the next original would be fed while
the first original was at the inverter tray and an original
jam would occur.
