  3. Cleaning the toner mark/side verify sensor

    Clean the area under the toner mark/side verify sensor (2) as follows:

    1. Loosen the thumbscrew (1).
    2. Flip the sensor up so that you can access the area under the sensor.
    3. Use a toner-certified vacuum cleaner to clean the bottom of the sensor and the surrounding area (3).
    4. Flip the sensor back into place.
    5. Tighten the thumbscrew.
    Note:
    The toner mark/side verify sensor is installed only on the 4100 and some versions of ID5/6 (4000) and therefore may not be installed on your printer.
  4. Cleaning the skew sensor

    Notes:
    1. You will need a long-handled nylon bristle brush to clean the skew sensor. Ask your service representative to provide the brush (IBM P/N 451555).
    2. Hold the tension arm down so that it stays aligned with the blue mark on the guide notch while you do the following steps. Otherwise, the 079A CHECK TENSION ARM message appears when you turn on the forms path vacuum, and you must do the Check Tension Arm procedure.

    Clean the skew sensor as follows:

    1. Turn off the forms path vacuum by pressing the Vacuum Push Button. The Vacuum-Off Warning Indicator flashes and then stays lit.
    2. Lift the paper off the tractor pins and move it aside so that you can access the skew sensor and the surrounding areas.
