  • Page 16: Mechanism

    1.Detailed Descriptions Mechanism Straight Paper Ejection Mechanism Paper ejected from the printer unit is transported by a transport roller and eject roller via an entrance roller. These are driven by entrance motor, transport motor and eject motor which permit linear speed correspondence.

  • Page 17: Staple Eject Mechanism

    1.Detailed Descriptions • Return to original position: Leading edge of succeeding sheet passes transport sensor The shift roller detects the home position by the shift roller HP sensor. The shift motor operates CW/CCW, and shifts the paper from front to back. The home position is located at the back of the displacement range, and is detected by the shift roller HP sensor.
  • Page 18 1.Detailed Descriptions Positioning roller ascent/descent mechanism The positioning roller unit is made to ascend/descend by a positioning roller motor (the motor operates CW/CCW), and its position is detected by the positioning roller HP sensor. The positioning roller rotates in the opposite direction to the transport roller, and has the function of transporting paper to the back of the staple tray.
  • Page 19 1.Detailed Descriptions • If Corner Stapling on B5 SEF or Larger Paper The movement is basically the same except that the front jogger fence, not the rear jogger fence, moves for paper alignment when the paper is fed into the tray. The jogger fences (rear and front) stand by 7 to 12 mm away from the paper, and again moves 7 mm [A] towards the paper in order to perform paper alignment, so it moves a total of 14 to 19 mm [B].
  • Page 20 1.Detailed Descriptions Description Description Stapler HP sensor Stapler retreat motor Stapler The stapler moves from the home position to the paper size to be stapled, and temporarily stands by. Next, the paper is transported, and after the jogger operation (paper alignment), stapling is performed. The following picture shows the stapler standby position according to various stapling positions.

  • Page 21: Paper Press Mechanism

    1.Detailed Descriptions Paper Press Mechanism For ejected paper, a paper press unit is provided to immobilize the paper above the tray. It is driven by the stack height lever motor (motor operates CW/CCW) The paper press unit is provided with a paper surface sensor which detects the upper part of the paper, and the stack height lever HP sensor which detects the home position of the paper press unit.
