2.1.5 Trimming Mechanism
1. When a corner of the laminated document is inserted over the T-cutter plate, the T-
sensor lever operates a leaf switch (TRI) that detects the document.
2. When the document is detected, the motor gear of the SG Motor rotates from its
reference position to the prescribed position to rotate the Control cam gear in the
direction of the arrow (counterclockwise) via a series of gears.
3. Rotation of the Control cam gear forces the T-cam roller to move vertically, such
that T-lever also moves vertically, rotating around its pivot.
4. As T-lever moves vertically, the T-cutter assy mounted on the end of T-lever moves
up and down, trimming the corner of the laminated document into a rounded radius.
