II UNIT EXPLANATION Q5686A/Q5687A CONVEYANCE B. Open/close control of the paper exit opening (1) Staple mode (when the length of the paper feed direction is over B5R) An finisher operation signal from the finisher rotates the paper exit opening motor (M708) to open the paper exit opening. Upon completion of the stapling operation, M708 turns on again to start to close the paper exit opening, and it stops when the paper exit opening HP sensor (PS712) detects the closing position. This operation is repeated for each staple paper bundle.
