Starting Sensor deviates from its
default position, or is broken. 1. Perform the "Key / Sensor" test in Sec. 9.3.6 to
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

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
