Classified Code ST1
U13 13
(Conveyor Jam 2)
: Paper did not
reach the Paper
Jam Sensor.)
Possible Cause
ST2 ST3 ST4
00 00 00 1. Document remains between
Starting Sensor and Paper Jam
Sensor.
2. Paper dust exists on or around
Paper Jam Sensor.
3. Paper Jam Sensor does not work
correctly.
4. Mechanical problem (Drive
Rollers, Conveyor Rollers, Drive Belt,
Conveyor)
Remove the document from the scanner.
1. Blow off the dirt with the accessory
blower. (See Sec.7.)
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. CN5019 (PAPER JAM SENSOR
Board) to CN5017 (POINTER Board)
b. CN5013 (POINTER Board) to CN5008
(POWER RELAY Board)
c. CN5032 (POWER RELAY Board) to
CN1012 (CONTROL Board)
4. Check the following signals.
a. JAM signal (CN5019-1
st
1 pin, CN5013-2
pin, CN5032-30
pin)
→ 0 V (when none exists on the
Paper Jam Sensor)
b. Check the reference signals for the
PJAM signal on the CONTROL Board.
→ IC1015-13
→ IC 1017-11
c. Check comparator output signal.
→ IC1017-13
(When no paper exists)
5. Replace faulty parts or board.
1. Check the Pointer's mechanical position
and Pointer Detector's status.
2. Execute Conveyor Motor test in
Sec.9.3.6 to check the mechanical
condition.
3. Check whether the Drive Rollers (2, 3),
Conveyor Rollers (1, 2) and Drive belt,
and whether the conveyors to support the
Drive Rollers and Conveyor Rollers are
put together into the scanner, properly.
4. Check the surfaces of the Drive Rollers
(2, 3) and of the Conveyor Rollers (1, 2).
a. Configuration:
Do the rollers swell irregularly?
→ Replace the rollers.
b. Whether the roller surfaces are dirty
→ Clean the surfaces.
5. Check whether the Drive Belt tension is
proper.
→ Re-adjust the belt tension.
