I I I I Saddle stitch function
The saddle stitch finisher can automatically place
two staples for centreline binding of prints or copies
and fold them along the centreline.
I I I I Hole punching (only if a punch module is installed)
If the saddle stitch finisher is equipped with a hole
punch module, printed paper can be hole punched
and delivered to the offset tray. Saddle stitching
and hole punching cannot be selected at the same
time. The automatic image rotation will not function
when the hole punching function is used.
For the allowed paper sizes for punching, see the
specifications on page 3-3.
When using the punch function in copy mode,
place the original with the top toward the inside of
the machine. If the original is not placed in this
orientation, punching will not take place at the
correct positions. (See "Standard original setting
orientation" on page 4-7 of the copy section.)
