Tray Paper Detection
Paper End/ Paper Near End Detection
When the tray runs out of paper, one end of the paper end feeler [A] drops through the cut out on the
bottom plate into the gap while the other end of the feeler pops up into the paper end sensor (S1) [B]
and turns it off. When paper end is detected, the paper out message is displayed on the operation
panel.
This machine is provided with a new paper near-end sensor.
A paper near-end feeler [C], installed on the corner of the bottom plate, detects the bottom plate as it
rises. As sheets of paper feed out, the bottom plate rises. This also raises the feeler of the paper near-
end sensor (S2) [D] until it blocks the gap of the sensor and switches it off. Paper near-end is detected
when there are about 75±50 sheets of paper (0.1 mm thick) remaining in the tray. When paper near-end
is detected, the operation panel displays the paper near-end message.
If paper end is detected before paper near-end, paper end takes precedence.
Paper Size Detection
When the paper tray is set in the machine, the paper size dial [A] installed on the right corner of the of
the tray pushes onto the three grooves of the paper size switch (SW1) [B]. This sets the reading for the
dial paper size setting. When more than one of these switches are set to "L" (ON") the machine knows
the paper tray is installed.
