Descriptions
Paper feed/separation
The paper feed/separation mechanism for the by-pass feed table is based on the
FRR method.
A spring [A] pulls the pick-up roller [B] towards the paper. When the solenoid [C] is
turned on, the pick-up roller lowers and feeds the top sheet of paper in.
A one-way clutch inside the paper feed roller [D] prevents reverse revolution.
The separation roller turns in the opposite direction to the paper feed roller. The
separation roller axle has a torque limiter made of a plastic coil spring. When the
applied load exceeds a certain limit, the separation roller turns in the forward
direction.
Paper end detection
When there is no paper on the by-pass feed table, the actuator [A] falls into the
notch in the table. This causes the paper end sensor (a photointerrupter) [B] to trip.
