Cutting Leading and Trailing Edges (X-cutter Mechanism)
1. All the rollers which feed the document stop when the cut position at the leading
edge of the document reaches the cutting position of the rotary cutter and fixed-
blade cutter.
2. The DC motor rotates to drive the carriage in the X-cutter assembly via the spiral
mechanism (not illustrated).
3. As the carriage makes a reciprocal movement, the rotary cutter attached to the
carriage moves against the fixed cutter to cut the compressed leading edge of
the document.
4. The rotation of the rollers which feed the document restarts when the cutting of
the leading edge is complete. Then, when the cut position at the trailing edge of
the document reaches the cutting position of the rotary cutter and fixed-blade
cutter, the feed rollers stop again.
5. The document trailing edge is cut in the same way as the leading edge, by a
reciprocal movement of the rotary cutter attached to the carriage.
6. The rotation of the rollers restarts to feed the laminated document from the eject
gate after the cutting of the trailing edge is complete.
