CHAPTER 2 OPERATION OVERVIEW

12.3.2 Inlet flapper control

a. Overview
The feed route is switched according to the size of the paper by movement of the two
flappers at the paper inlet. This has the following two purposes:
1) Detection by the sensor of the passing of the trailing edge of the paper according to size.
2) Prevention of the next sheet of paper from hitting the top of the existing stack.
The table below shows which sensors are used for which size paper.
Sensor
Paper sensor 1 (PI60)
Paper sensor 2 (PI61)
Paper sensor 3 (PI62)
The flappers are driven by their respective solenoids according to paper size as shown be-
low.
