8. DFP Pressure Motor circuit does
not work properly.
1. Check the following connection and
soldering condition on each connector.
CN1002 (CONTROL Board) to CN4003
(DRIVE Board)
2. Check the soldering condition of IC4018
and its surrounding parts.
3. Check the following signals on the
DRIVE Board.
a. IC4018-2nd pin (ENABLE)
b. IC4018-14th pin (CLK)
c. IC4018-17th pin (DIR)
d. IC4018-15th pin (REF)
4. Check the soldering condition of IC0015
on the CONTROL Board to repair it.
5. Replace faulty parts or boards.
9. Paper Feed Roller module or
DFP Roller is not assembled
properly.
Refer to the 1st item on Classified Code U11.
10. Rollers (Paper Feed,
Separation, DFP) are dirty.
Refer to the 2nd item on Classified Code U11.
11. Rollers have reached their life
expectancy.
Refer to the 3rd item on Classified Code U11.
U13 (Conveyor Jam2:
Paper did not reach the
Starting Sensor.)

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.
3. Starting Sensor does not work,
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)
b. CN2006 (USS RELAY Board)
to CN1008 (CONTROL Board)
4. Check the following signals.
a. STARTING signal (CN2008-1st pin,
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.
IC0017-8th pin: 3.3 V
(when no document exists)
5. Replace faulty parts or boards.
