Stapler unit operation

The stapler unit uses the stapler unit motor (M104), staple cam, staple press head plates, staple arm, and support base to staple media together. The staple mode is enabled by using the printer’s settings (see “Stapler/stacker submenu” on page 51). The stapling procedure begins when media enters the staple guide and the DC controller PCA sends the end-of-job signal to the stapler/stacker driver PCA.
