8.5 Feed motor control circuit
The feed motor is a DC motor driven by the control signal output from the PFC CPU and ASIC on the
LGC board and rotates the pick-up roller, feed roller, separation roller and transport roller for each
drawer, the tandem LCF and bypass unit.
When the ON/OFF signal (PFMON-0) output from the PFC CPU is L level, the feed motor is driven at a
speed based on the frequency of the reference clock signal (PFMCK-1) output from the ASIC.
