Q6. Staples are not diagonal when using corner stapling.

A6. The stapler can staple at the far side and the near side, as seen from the operating perspective.

To use far-side stapling, from the [UTILITY] screen, go to [Administrator Setting] - [System Setting] - [Expert Adjustment] - [Corner Staple(Back) Angle] and select [Diagonal].

If you wish to change the position of diagonal staples (top left/top right), change the orientation of the papers 90 degrees so that they are stapled at the far side.
