Sub Height Sensors
Two sensors (sub-height sensors [A]) have been added to detect the height of the stapled sheets.
When sheets stapled at one point (corner stapling) are stacked, the sensors prevents the sheets from
hitting the paper guide, edge guide, or the next stapled booklet as they are stacked up. When one of
the sensors detects the sheets, the machine stops the job in progress.
