Detects the leading edge and trailing edge of
each sheet as it passes from the jogger unit
above and into the horizontal feed path of the
duplex unit below. Signals a jam if the paper
does not arrive at or reach the sensor location at
the prescribed time.
At power on, detects the actuators on the jogger
fences of the duplex unit, switches off the jogger
motor and stops the fences at their home
positions.
Receives the light emitted from the double–feed
detection LED and reflected from the surface of
each sheet in the paper path. Signals an error if
the thickness of the paper is not the same as the
previous sheet.
Detects the position of guide plate when the jam
occurs between the vertical transport rollers and
registration roller.
Detects jams at the top of the vertical paper
path.
Detects the leading edge of the paper and
switches off the registration motor and stops the
registration roller briefly but long enough to
correct buckle the paper.
Detects the leading and trailing edge of each
sheet at the paper exit slot to check timing and
