CHAPTER 2 BASIC OPERATION
5.
Stack Return Jam (82H)
The returning roller does not reach the returning roller home position sensor after it has
supposedly been moved over the distance by the stack processing motor (M2). Or, it does not leave
the returning roller home position sensor after it has supposedly been moved over the distance.
A check for this type of jam is made while paper is being moved. If the foregoing condition is
detected during initialization, it will be identified as an error.
