Starting Sensor.)
13 00 00 00 1. Document remains between
Starting Sensor and Slip Detect
Sensor.
Remove the document from the scanner.
2. Paper dust exists on or around
Starting Sensor.
1. Clean up the dirt with cleaning paper or
cotton swab or soft and dry cloth.
(See Sec.7.)
2. Execute Key/Sensor and Sensor Sensitive
Level tests in Sec. 9.3.6 to check the sensor
condition.

correctly.
1. Execute Key/Sensor test in the Sec. 9.3.6 to
check the sensor condition.
2. Check 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. CN3007 (STARTING SENSOR Board)
to CN2008 (USS RELAY Board)

CN1008-3rd pin)
 Approx. 1 V (when nonexistence on the
Starting Sensor)
b. Check the reference signal for the
STARTING signal on the CONTROL
Board.
 IC0023-3rd pin: 1.5 V or less
 IC0025-2nd pin: Approx. 1.5 V
c. Check comparator output signal.
