Error
Possible Cause
ST3 ST4
00 00 1. Conveyor Roller, Exit Roller, or
Free Roller is dirty.
2. Conveyor Roller, Exit Roller, or
mechanical parts
(Conveyor, Belt) related to
XX 00
conveying document are
not installed properly.
3. Conveyor Roller or Exit Roller
has reached their life
expectancy.
4. Starting Sensor's arm does
not come back to the default
position.
5. Scanned document is out of
specifications regarding the
length. (Refer to paper
specifications.)
00 00 1. Document remains in the
scanner.
2. An arm of Paper Sensor or
Starting Sensor deviates from its
default position, or is broken.
3. A Dust exists around Paper
Sensor or Starting Sensor to
prevent the sensor from working
correctly.
00 00 1. ADF Door remains open or is not
closed properly.
2.The claw of the cover is broken
not to interrupt the Door Sensor.
3. The claw position is not matched
to the Door Detector's position
so that door open- closed status
cannot be detected.
4. The Door Detector or its monitor
circuit does not work, correctly.
