Cutter Mechanism (Border Mode)

The cutter mechanism cuts the laminated document to the size of the document plus an
added border. Both edges of the films are cut to suit the width of the document and the
leading edge and trailing edge are cut according to the document length.
Y-Cutter Vertical Drive Operation
1. The TC motor rotates clockwise from its reference position to drive the cam
clockwise via a series of gears. The cam rotates the Y-diversion lever clockwise
about its pivot. (All rotations indicated by arrows. )
When the Y-diversion lever reaches its maximum displacement position with the
cam at approximately its 180 ‹ rotated position, rotation of the TC motor pauses.
2. When the Y-diversion lever reaches its maximum displacement position, its
movement lowers the two Y-cutter blades from the standby position to the
cutting position, where they start cutting the edges of the laminated film.
3. When the Y-axis cutters reach the trailing edge cutting position, the TC motor
starts rotating again and stops when it reaches its reference position. This
rotation returns the cam and Y-diversion lever to their original positions and the
cutters move to their standby positions.
