At pickup, the Pickup Roller picks up a paper by coming down and contact with paper surface. The Pickup Roller comes down when the Pickup Solenoide turns ON. A paper picked up by the Pickup Roller is fed to the feed path with the Separation Roller, and then, is fed to the Registration Roller with the Vertical Path Roller. The Vertical Path Roller, Pickup Roller, Feed Roller and Separation Roller are driven by the Cassette Pickup Motor.

Thus, delay and stationary jam detection are not executed at the Cassette Pre- Registration Sensor. Instead of it, the Vertical Path Sensor executes the delay and stationary jam detection. Since the residual jam should be detected on each cassette, the Cassette Pre-Registration Sensor detects it. Because the Vertical Path Sensor is too close and it is unnecessary to execute detection, the Vertical Path Sensor does not execute residual jam detection.
