Open/close Sensor
<2> Inserter Paper exit Sensor (HI_SEN)
HI_SEN uses the photointerrupter integrated with an LED and a pho-
totransistor.
The sensor detects a sheet with the lever actuator interrupting the light
path of the photointerrupter.
The signal is transmitted to the CPU (IC6-Pin106) through the noise fil-
ters (R25,C9).
The signal input to the CPU follow the logic: "L" when a sheet is
detected, "H" when not detected.
R39 is a current limiting resistor for the LED. R34 is a load resistor for
the sensor.
<3> Inserter Reverse unit Open/close Sensor (HYK_SEN)
HYK_SEN uses the photointerrupter integrated with an LED and a
phototransistor.
The sensor detects state of the reverse unit with the lever actuator
interrupting the light path of the photointerrupter.

Inserter Empty Sensor
Inserter Registration Sensor
Inserter Timing Sensor
<5> Inserter Set Sensor (S_SEN)
S_SEN uses the photointerrupter integrated with an LED and a pho-
totransistor.
The sensor detects the main unit with the lever actuator interrupting the
light path.
The signal is transmitted to the CPU (IC6-Pin2) through the noise fil-
ters (R56,C16).
The signal input to the CPU follows the logic: "H" when the inserter is
connected to the main unit, "L" when not connected.
R59 is a current limiting resistor for the LED. R58 is a load resistor for
the sensor.
<6> Inserter Empty Sensor (EMP_SEN)
EMP_SEN uses the photointerrupter including the LED and the pho-
totransistor in one unit.
The sensor detects a sheet with the lever actuator interrupting the light
path.
The signal is transmitted to the CPU (IC6-Pin31) through the noise fil-
ters (R7,C4).
The signal input to the CPU is the following logic: the signal is "H" when
a sheet is detected, "L" when not detected.
R12 is the current limiting resistor for the LED. R11 is the load resistor
for the sensor.
The signal is transmitted to the CPU (IC6-Pin108) through the noise fil-
ters (R21,C7).
The signal input to the CPU follows the logic: "L" when the reverse unit
is open, "H" when closed.
R37 is a current limiting resistor for the LED. R32 is a load resistor for
the sensor.
<4> Inserter Stand cover Open/close Sensor (KC_SEN)
KC_SEN uses the photointerrupter integrated with an LED and a pho-
totransistor.
The sensor detects state of the chassis cover with the lever actuator
interrupting the light path.
The signal is transmitted to the CPU (IC6-Pin109) through the noise fil-
ters (R29,C11).
The signal input to the CPU follows the logic: "L" when the chassis
cover is open, "H" when closed.
R41 is a current limiting resistor for the LED. R36 is a load resistor for
the sensor.
<7> Inserter Registration Sensor (REG_SEN)
REG_SEN uses the photointerrupter integrated with an LED and a
phototransistor.

path.
The signal is transmitted to the CPU (IC6-Pin32) through the noise fil-
ters (R14,C5).
The signal input to the CPU follows the logic: "L" when a sheet is
detected, "H" when not detected.
R17 is a current limiting resistor for the LED. R16 is a load resistor for
the sensor.
<8> Inserter Timing Sensor (TIM_SEN)
TIM_SEN uses the photointerrupter integrated with an LED and a pho-
totransistor.
The sensor detects a sheet with the lever actuator interrupting the light
path.
The signal is transmitted to the CPU (IC6-Pin33) through the noise fil-
ters (R19,C6).
The signal input to the CPU follows the logic: "L" when a sheet is
detected, "H" when not detected.
