AR-CF2 ELECTRICAL SECTION 9 - 4

<2> 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> Reverse Unit Open/Closed 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.

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> Chassis Cover Open/Closed 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.

<5> 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> 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.

<7> Registration Sensor (REG_SEN)

REG_SEN uses the photointerrupter integrated with an LED and a
phototransistor.
The sensor detects a sheet with the lever actuator interrupting the light
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> 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.
R18 is a current limiting resistor for the LED. R31 is a load resistor for
the sensor.
