If the pinchwheel lever is  when the Pinchwheel Down / Stop..." message is
displayed on the frontĆpanel, then the test has failed.
If the pinchwheel lever is  when the Pinchwheel Up / Stop..." message is
displayed on the frontĆpanel, then the test has failed.
If the test fails, try replacing one of the following components:
1 Pinchwheel sensor page 6Ć21.
2 PinchĆarm assembly page 6Ć57.
3 Main PCA page 6Ć9.
Only replace one component at a time and perform the “Pinchwheel Sensor” test again before
replacing another component. Using this procedure you will be able to determine exactly which
component failed.
