Remaining Paper/Paper End Detection –
Tray 2
Remaining paper: Measured by
the lift motor rotation angle
Paper end: When no light is
reflected back to the sensor, paper
end is detected

This is the same as the B234 series (Katana-C1).
As stated previously, the machine detects the amount of remaining paper by
counting lift motor pulses. There are 4 levels of output.
The slide explains what happens when paper runs out.
¾ Tray 1 paper end works in a different way. There is a cutout and a sensor –
1st paper end sensor. There is another sensor under the right half of the
tandem tray, the right 1st tray paper sensor. This sensor is used when the
tray is put in the machine. If it detects paper, the lift motor lifts the tray. This
will be described later, in the Tandem Tray section.
