Thats a Glass-copy. Thats a story on its own

Thank you so much for the information! I'm going to try out this soon and report back. I have a couple of questions in the meantime. How do I identify the flag out of place? Is this the same as sensor PS28 that teckat refers in his post and shows in the diagram?

I call it a flag, it is the part that actuates the sensor. Look right after the sep pad on top. You can tell if you know where to look. Plastic part of actuator that sticks up that paper hits. Once people open up doc feeder to clear jams they quit knocking it out.
