I. BASIC OPERATION
A. Outline
The paper deck feeds print paper to the printer.
The sequence of paper deck operations is controlled by the paper deck driver PCB. This PCB
contains an eight-bit microcomputer (IC201) to control the sequence of operations and serial
communication with the option controller PCB.
The paper deck driver drives the solenoids and motors according to various commands
coming from the option controller through the serial communication line. The paper deck
driver sends sensor and switch data to the option controller through the serial communication
line.
