The document feeder on my WorkCentre 7120 doesn’t do anything when copying or scanning. Paper is not drawn and the green light on it that I see in videos isn’t on; no sign of any activity. When copying, the printer simply prints out a copy of the nonexistent paper on the document glass. In addition, the machine does identify a fault, this being it doesn’t recognize the feeder cover being closed despite it being so. The cover is also unable to stand up on its own when opened without manually holding it up. Could this be related to the feeder not drawing in paper? What could be causing this issue?
Yes the hinges that hold the feeder open could be the problem. Sometimes the screws that hold the hinges in place strip or pull out of the plastic frame. You can replace the feeder. Try and fix the broken hinge. Or add a little piece of electrical tape to extend the little black plunger the feeder pushes down when closed on the scanner. Left side of scanner
