Theory of Operation Ver2.0 Aug.2005
B. Paper exit opening/closing control
(1) Stapling mode (when 51 or more sheets of paper are stapled with the size in the sub scan direc-
tion shorter than B5R)
When the stacker entrance sensor (PS5) detects [1] the leading edge of the 51st sheet of paper while in the
paper stack, the paper exit motor (M8) turns ON to open the paper exit opening. As a result, when the paper exit
home sensor /2 (PS100) turns OFF [2], M8 turns OFF to maintain the open/close angle of the paper exit open-
ing.
When the alignment (close) of the last paper to be stapled is completed [7], the stapling operation starts. At the
same time, M8 also turns ON to close the paper exit opening. As a result, when PS100 turns ON, M8 turns OFF.
The open/close angle at this time is at the home position, which is maintained until the stacking operation of the
50th sheet of paper for the next stapling is completed.
