2.2 BASIC OPERATION
2.2.1 PICK-UP AND SEPARATION
The ARDF uses an FRR (feed & reverse roller) system.
Setting paper moves the feeler, causing the original set sensor to inform the
CPU that the ARDF is ready to feed.
Press
→
short time lag
→
DF feed clutch engages
→
DF motor starts.
The 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.
2.2.2 CLUTCH OPERATION
The DF feed clutch is provided to stop feeding when the original is fed to the inverter tray in
double-sided mode. If the DF feed clutch does not stop the pick-up, feed and separation
rollers in double-sided mode, the next original is fed while the first original is at the inverter
tray and an original jam occurs.
2.2.3 ORIGINAL TRANSPORT AND EXIT
Single-Sided Originals
The feed motor feeds the separated original to the registration roller [A]. A short time after
an original reaches the registration sensor [B], the DF feed motor stops briefly, the scanner
moves to DF scan position, and the white peak is read. The DF feed motor and DF
transport motor then start and the sheet is scanned.
After scanning, the original is fed out by the exit roller [C].
