[9] CIRCUIT DESCRIPTIONS
1. Outline
The finisher main circuit transmits and receives data to and from the
copier main PWB. According to instructions from the copier, it controls
loads, sensors and the input of switching information.
The finisher main circuit consists of a circuit which receives signals
from sensors and switches, a circuit which drives solenoids and
clutches, CPU, ROM, expansion I/O and other peripheral circuits.
