PAPER END DETECTION
2.3 PAPER END DETECTION

A861D105.WMF
If there is some paper in the paper tray, the paper stack raises the paper end feeler
[A] and the paper end sensor [B] is deactivated.
When the paper tray runs out of paper, the paper end feeler drops into the cutout
[C] in the tray bottom plate and the paper end sensor is activated.
When the paper tray is drawn out with no paper in the tray, the shape of the paper
end feeler causes it to lift up.
