(Waiting Sensor
adjustment error)
Possible Cause
ST2 ST3 ST4
00 00 00 4. Hopper Home Detector does not
work correctly.
00 00 00 1. Paper dust exists on or around
the Waiting Sensor.
2. Waiting Sensor does not work
correctly.
1. Check the alignment of Hopper Home
Detector and its actuator is proper.
2. Execute Key / Sensor test in Sec.9.3.6 to
check the sensor condition.
3. Check the following connection and
soldering condition on each connector.
a. CN5012 (HOPPER HOME Board) to
CN5010 (RELAY (LOWER) Board)
b. CN5007 (RELAY (LOWER) Board) to
CN1013 (CONTROL Board)
4. Check the soldering condition of IC5002
and its surrounding circuit on the
HOPPER HOME Board, and of IC1036
and its surrounding circuit on the
CONTROL Board to repair it.
5. Check the following signals.
HOPPER_HOME signal (CN5012-8
on the HOPPER HOME Board, IC1036-3
pin on the CONTROL Board)
→ Approx. 3.3 V (when the actuator
interrupts the detector)
6. Replace faulty parts or boards.
1. Blow off the dirt with the accessory
blower. (See 7.2.)
2. Execute Key / Sensor and Sensor
Sensitive Level tests in Sec.9.3.6 to
check the sensor condition.
1. Execute Key / Sensor and Sensor
Sensitive Level tests in Sec.9.3.6 to
check the sensor condition.
2. Check whether the sensor alignment is
proper (whether the sensor direction faces
to its reflector).
3. Check the following connection and
soldering condition on each connector.
a. CN5027 (WAITING SENSOR Board)
to CN5025 (RELAY (UPPER) Board)
b. CN5022 (RELAY (UPPER) Board) to
CN1014 (CONTROL Board)
4. Check the following signals.
a. WAITING signal (CN5027-3
CN5025-3
→ 0 V (when none exists on the
Waiting Sensor)
b. Check the reference signal for the
STBY signal on the CONTROL Board.
IC1014-2
IC1016-5
c. Check comparator output signal.
→ IC1016-2
(when no paper exists)
5. Replace faulty parts or boards.
