The Stacker Upper Limit Sensor detects the Stacker Tray at the upper limit during ascension,
or does not detect a change of state during descension
Initial Actions
Refer to BSDs 12.1 and 12.15 for the following procedure.
Procedure
Remove the Rear Lower Cover. The Stacker Upper Limit Sensor is blocked by the Actua-
tor.
