The staple function can be used to staple output.
This function saves considerable time when preparing materials such as handouts for a meeting. The staple function 
can also be used in combination with 2-sided printing to create materials with a more sophisticated appearance.
Stapling positions and the number of staples can be selected to obtain the following stapling results.

To punch holes in the output, click the [Punch] checkbox so that a checkmark 

 appears. Punch hole positions can be 

set using [Binding Edge].

• To use the staple function, a finisher is required.

• To use the punch function, a punch module must be installed on the finisher.

• The number of holes that can be punched and the spacing between the holes varies depending on the installed punch 

module.

• The maximum number of sheets that can be stapled is 50 sheets (30 sheets for Foolscap, B4, or larger sizes).

• The staple function and offset function cannot be used at the same time.

• When the finisher is disabled in the machine's system settings (administrator), the staple function and punch function 

cannot be used.

• When the staple function or the punch function is disabled in the machine's system settings (administrator), stapling or
