Subtray exit control

When exiting the paper to the subtray, the paper is prevented to be misaligned by releasing the nipping of the
subtray exit roller by the roller release solenoid /4 (SD4) to nip the paper only at the trailing edge and slowing
down the paper by the subtray exit roller that is rotating in low speed for every paper. The horizontal conveyance
sensor /1 (PS2) [1] and the subtray exit sensor (PS11) [2] detect the paper exited to the subtray.

The roller release solenoid /4 (SD4) turns ON [2] to release the nipping of the subtray exit roller [3] after a speci-
fied period of time since the horizontal conveyance sensor /1 (PS2) detects the leading edge of paper [1]. SD4
turns OFF [5] and the subtray exit roller nips at the trailing edge of paper [6] after a specified period of time since
PS2 detects the trailing edge of paper [4]. This control is conducted for every paper exited to the subtray.

Subtray paper full detection control

The subtray paper full detection is conducted by the subtray paper full sensor (PS12) via the actuator.
PS12 turns ON under normal circumstances. The subtray paper full condition is detected and the subtray paper
full signal is transmitted to the main body when the actuator is pressed by stacked paper and PS12 turns OFF.
Then, the main body displays the message on its operation panel.
