Calibrating the multifeed sensor

In order for the multifeed sensor to function properly and to detect the presence of multifeed media, the sensor must be properly calibrated. Any time a new multifeed sensor is replaced, this procedure must be followed:

1. Open the ADF, and remove the separator pad. Close the ADF.
2. Obtain a multifeed sensor calibration sheet (included with the multifeed sensor FRU), and fold it in half such that the short edges overlap each other.
3. Load the multifeed sensor calibration sheet into the ADF with the folded edge first.
4. Enter the Diagnostic Mode and select Scanner Tests > Ultrasonic Multifeed Sensor Calibration.
5. Press the Submit button to begin the calibration procedure. The calibration sheet will be fed into the ADF.
   The test will report if the calibration procedure passed or failed. If the test reports “Passed,” then the calibration process is successfully complete. If the test reports “Failed,” then the calibration process failed to complete. If the calibration test fails, then check the following:
   • Make sure the separator pad is removed.
   • Make sure the calibration page is folded over and feeding into the ADF as two sheets.
   • If the problem continues, then make sure the multifeed sensor is properly installed and the cables are connected. if the problem continues, then replace the multifeed sensor.
