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. 

The finisher block diagram is shown in Fig. 1.

The CPU (IC2) controls finisher loads and the system synchronously,
transmitting and receiving data to and from the copier main PWB
through the serial communication line. 

The HB/3040 is a high-performance single chip microprocessor using
the 32-bit H8/300H CPU as a core, integrating peripheral functions
necessary for system configuration. 

The HB/300H CPU has an internal 32-bit configuration and is
equipped with 16-bit 

×

 16 general-purpose registers and a simple,

optimized instruction set for high-speed operation. It can handle 16M
byte linear address space.

As peripheral functions, it contains ROM, RAM, 16-bit integrated
timer unit (ITU), programmable timing patter controller (TPC), watch-
dog timer (WDT), serial communication interface (SCI), A/D con-
verter, D/A converter, I/O port, DMA controller (DMAC), and refresh
controller.
