Punch Unit - Overview
This punch unit has two new mechanisms to
make the positions of punch holes more accurate
Skew correction
» The punch unit corrects skew in the paper before the
holes are punched.
Side-to-side movement of the punch unit
» The paper must be in the middle of the paper feed path,
or the punch holes will be too high or too low along the
edge of the paper.
» The punch unit detects the distance that the paper is
away from the ideal position.
» Then it moves the punch unit across to put the holes in
the correct position at the edge of the paper.
The mechanism is the same as the punch unit for the B793, but the layout is a bit
different.
