In order to staple 100 sheets (the maximum allowed), the finisher is equipped with a mechanism that does not allow the paper exit to open or to output or to output the stapled document onto the tray.
- When staple is ON, the exit guide plate motor goes ON and opens the paper exit, then after staple goes OFF the feed-out belt motor [A] goes ON and the stack hooked by the pawl on the moving feed-out belt [B] is transported to the paper ext and then on to the shift tray.
- At this time if the stack is large (move than 350 mm thick), the stack is output supported by the positioning roller.
- Once the operation of the feed-out belt motor feeds the stack the prescribed distance, the paper exit motor switches ON and starts rotating the paper exit roller, and this rotation together with the feed-out belt pawl on the belt moves the stack out the paper exit and then on to the shift tray.
- After the paper exit motor switches ON the stack feeds the prescribed distance, the exit guide plate motor switches ON and the exit guide closes. This operation of the paper exit roller moves the stack out of the finisher onto the shift tray.
- The paper exit opens and closes in staple mode when more than 16 stacks are output.
- A rotation of a disc mounted above the exit guide plate motor controls the OFF timing of the exit guide plate motor that operates the opening and closing of the exit.
- Also, the position of the feed-out belt is monitored by the feed-out belt HP sensor [C].
