  • Page 83: Paper Feed Mechanism

    Met-C1yz Training Paper Feed Mechanism  The leading edge of the paper is detected by the entrance sensor [G].  If shift mode is used, the shift rollers [A] and [B] move the paper until the side-to-side registration sensor [E] can detect the rear edge of the paper.
  • Page 84 Met-C1yz Training Straight-through Feed  Paper from the mainframe goes to the paper output rollers [C] and [D], and on to the shift rollers [A] and [B].  The transport motor drives the rollers in the paper feed path.  When shift mode is used, the shift motor moves the shift rollers from side to side.

  • Page 85: Shift Mechanism

    Met-C1yz Training Shift Mechanism  The shift mechanism starts when the distance between the trailing edge of paper and the paper output roller on the main frame is 10mm (timing is based on motor pulses and leading edge detection by the entrance sensor).

  • Page 86: Pressure Release Mechanism
