2.5 Detecting Jams
2.5.1 Overview
0023-7229
The paper deck is equipped with 2 sensors.
The machine reads the signals from the sensors at such times as programmed in the host machine's DC controller.
The machine decides whether the movement of paper is normal or not by using the host machine's DC controller.
<if a jam is identified>
The machine delivers the paper moving ahead of the jam, and then stops its operation. Thereafter, it indicates instructions on the removal of the jam using the host
machine's control panel.
