The jogger fences [B] are opened and closed by the jogger motor [A]. At the start of jogging, the
jogger fences [B] stand by in a state where they are opened wider than the paper width.
When the rear edge of the transported paper is pressed against the trailing edge fence by the
reverse roller, the jogger fences move close to the edges of the paper.
Next, the jogger fences move to the edges, to align the paper.
After jogging is complete, the jogger fences again open, and stand by to receive the next sheet.
The home position of the jogger fences is detected by the jogger HP sensor [C].
Paper exit guide plate open/close mechanism
When paper is stacked in the stapler tray, the paper exit guide plate [A] is opened to cancel the
load on the paper exit roller.
When paper is stacked in the stapler tray, the paper exit guide plate remains open from the first
page to the last page, and after the stapling operation is finished, the paper exit guide plate is
closed, and the paper is ejected by the paper exit roller and release belt.
The switching action of the paper exit guide plate is driven by the paper exit guide plate open/
close motor [B] via a link.
The home position of the paper exit guide plate is detected by the paper exit guide plate open/
close HP sensor [C].
