2. Perform the "Feed" test to check paper feed
mechanism.
3. Conveyor Roller or Exit Roller
has reached their life
expectancy.
1. Replace the Conveyor Roller or Exit Roller after
checking each roller configuration and scanner
counter of Service Utility.
2. Perform the "Feed" test in Sec. 9.3.6.
4. Starting Sensor's arm does
not come back to the default
position.
1. Perform the "Key / Sensor" test in Sec. 9.3.6 to
check the arm condition, inserting or withdrawing a
document.
2. Re-position or replace the arm.

scanner.
18 00 00 00 1. Document remains in the
scanner.
1. Push the Door Open Button to open the ADF Door
and remove the document from the scanner.
2. An arm of Paper Sensor or
Starting Sensor deviates from its
default position, or is broken.

check the arm condition, inserting or removing or
withdrawing a document.
2. Check the arm's swing condition.
3. Re-position or remove it.
3. A Dust exists around Paper
Sensor or Starting Sensor to
prevent the sensor from working
correctly.

U30: Door open 20 00 00 00 1. ADF Door remains open or is not
closed properly.
1. Close the door surely.
2.The claw of the cover is broken
not to interrupt the Door Sensor.
1. Replace the cover.
3. The claw position is not matched
to the Door Detector's position
so that door open- closed status
cannot be detected.
1. Adjust each part position so that the claw can interrupt
the Door Detector.
4. The Door Detector or its monitor
circuit does not work, correctly.
1. Perform the "Key / Sensor" test in Sec. 9.3.6 to
check the sensor condition, repeating closing and
opening the door alternately.
