DETAILS OF MODIFICATION
To minimize drum scratches when removing the cleaning unit, a cleaning unit release mechanism has been added. When the drum stay is removed, the pressure bracket on the cleaning unit pushes the guide rail to make a gap between the pick-off pawls and the drum. In accordance with this modification, the shape of the positioning studs also has been modified to install the cleaning unit and the drum stay easily.
