Outline
The two flappers mounted at the paper inlet are operated to configure the feed path according to
the size of paper. The flappers are used to enable the following:
1.
To detect the passage of the trailing edge of the paper being moved by an appropriate sensor.
2.
To prevent the following sheet from butting against the top of the existing stack.
The relationship between sensors and paper sizes is as shown in Table 3-301.
