2. Paper dust exists on or around
the Exit Sensor.
1. Clean up the dirt with cleaning paper or
cotton swab or soft and dry cloth.
(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
to check the mechanical condition.
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.

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. Clean up the dirt with cleaning paper or
cotton swab or soft and dry cloth.
(See Sec.7.2.)
