4. Check the following signals.
a. ENDING signal (CN2004-1st or
CN1007-4th pin)
→
0 V (when none exists on the
Exit Sensor)
b. Check the reference signal for the
ENDING signal on the CONTROL Board.
IC0023-5th pin: 1.5 V or less
IC0025-6th pin: Approx. 1.5 V
c. Check comparator output signal.
→
IC0017-6th pin: 3.3 V (when no
document exists)
5. Replace faulty parts or cables.
4. Mechanical problem (Drive
Rollers, Drive Belt, Conveyor) 1. Execute Conveyor Motor test in Sec.9.3.6

(See Sec.7.2.)
2. Execute
Key/Sensor and Sensor Sensitive
Level tests in Sec. 9.3.6 to check the sensor
condition.
3. Mechanical problem (Exit Roller,
Drive Belt, Conveyor) 1. Execute Conveyor Motor test in Sec.9.3.6

2. Check whether the Drive Roller (3), Exit
Roller, Drive Belt, and the conveyor to
support the rollers are put together into the
scanner, properly.
3. Check the surfaces of the Drive Roller (3)
and the Exit Roller.
a. Configuration:
Do the rollers swell irregularly?
→
Replace the rollers.
b. Whether the roller surfaces are dirty
→
Clean the surfaces.
4. Check whether the Drive Belt tension is
proper.
→
Re-adjust the belt tension.
U18 (Paper remains in
the scanner) 18 xx 00 00 1. Document remains in scanner. Remove the document from the scanner.
2. Paper dust exists on a sensor. 1. Execute Key/Sensor and Sensor Sensitive
Level tests in Sec. 9.3.6 to define the sensor
that results in this problem.
2. Blow off the dirt on the surface of the sensor
with the accessory blower. (See Sec.7.2.)
