Trimming Mechanism

1. When a corner of the laminated document is inserted over the T-cutter plate, the
sensor lever operates a leaf switch that detects the document.
2. When the document is detected, the motor gear of TC motor rotates in the direction
of the arrow (counterclockwise) from its reference position to drive the T-cam gear in
the direction indicated by the arrow (clockwise) via a series of gears.
3. Rotation of the T-cam gear forces the T-cam roller to make a vertical movement,
such that T-lever1 moves vertically, rotating around its pivot.
4. As T-lever 1 moves vertically, the T-cutter mounted on the end of T-lever 1 moves
up and down, trimming the corner of the laminated document into a rounded radius.
