Gate drive mechanism The gate switches among the paper transfer path to the main tray, the one to the sub tray, and the one to the stacker. The gate motor (M12) [1] drives the gate cam [2], and then 2 cams /UP [3] and /Lw [4] of the gate cum drive the 2 gates /UP [5] and /Lw [6] respectively.

    4. CONVEYANCE SECTION Theory of Operation Ver2.0 Aug.2005 4.2.3 Bypass gate control A. Bypass gate drive mechanism The bypass gate is provided on the paper path to the stacker section, and conveys the next paper even while in the stapling operation. This is a gate to keep productivity at a high level with no loss time. The bypass gate solenoid (SD5) [2] drives the bypass gate [1].
  • Page 49 Theory of Operation Ver2.0 Aug.2005 4. CONVEYANCE SECTION B. Bypass gate control The bypass gate only operates for the small size paper (A4, B5, and 8.5 x 11) in the stapling mode. The FS con- trol board (FSCB) controls the bypass gate solenoid (SD5). When stapling 2 sheets of paper for 3 copies, SD5 operates as follows.

  • Page 50: Shift Control

    4. CONVEYANCE SECTION Theory of Operation Ver2.0 Aug.2005 4.2.4 Shift control A. Shift mechanism The FS conveyance motor (M1) drives the shift roller [4]. The shift roller moves itself backward to shift the paper while transferring the paper to the main tray. During conveying the paper to the main tray [1], the crank mechanism [3] shifts the shift movable section [5] including the shift roller approximately 30 mm backward [6] to shift and exit the paper when shift roller motor (M2) [2] rotates.
  • Page 51 Theory of Operation Ver2.0 Aug.2005 4. CONVEYANCE SECTION B. Shift control In the sort/group mode, the shift roller motor (M2) turns ON [2] and shifts the shift movable section a specified period of time after the FS entrance sensor (PS4) detects the trailing edge of the paper [1].
