Stapler

This section describes the operation of the stapler.

Stapling operation

Sheets of media fed from the punch are tamped on the compiler unit assembly, and then stapled at specified
positions by the command of the printer.

Staple positions

There are four stapling modes:
•
Front staple (corner) [Front Corner]
The stapler staples a set of media obliquely (45 degrees) after the rear tamper
aligns the media to the front side.
•
Rear staple (corner) [rear corner]
This type of stapling is applied for media with a width of 216 mm or more.
The stapler moves to the rear corner and staples a set of media obliquely (45
degrees) after the front tamper aligns the media to the rear side.
