If you open the back cover (depress the release button on the top right) If you lift it up look for two black anchors that grab the base when you close the lid. I have one that has a broken tab on the left side, which happens to be the same side as the cover closed switch. If the top is not closed all the way the rollers do not line up and the cover switch is not depressed to let normal operation. Also, if the switch arm is busted (case colored plastic push pin protruding from the cover) it will not make contact with the switch when closed. Try closing the cover and push down on left side of the fax. Does the error go away? If not, the actuator arm or the switch are bad.

Look to the left side of the flatbed glass for a thin strip of glass by itself. When you scan from the glass, the document stays put and the sensor moves across the document. When you scan from the feeder, the sensor stays in that glass strip and the document moves across the sensor. See what I mean? I would check the small feeder glass for dirt or scratches from staples or other flotsam. Also not a bad idea to blow out the feeder path with some compressed air to ensure the documents is handled smoothly. Hope this helps!
