Function
This detects the top of the paper entering and
then determines the timing to switch from the
hopping to the conveyor.
This detects the tip of the paper transferred,
then determines the length of the paper
according to the time it takes the tips of the
paper to reach the sensor.
This detects the tip and end of the paper, then
determines paper discharge.
This determines the tip of the paper entering
the double-side printer unit, then determines
the times it takes for the inverse roller to
inverse from CCW to CW.
This detects the tip of the paper after inversion
by the double-side printer unit.
After inversion by the double-side printer unit,
the end and tip of the paper is detected and
then paper discharge is determined.
This detects paper-full in the face-down
stacker.
This detects paper conveyance to the paper
discharge roller, then determines the timing to
offset job operations.
When the paper jams, this detects the paper
jam in the face-down conveyance rotor.
This detects the paper conveyed from the
option tray.
