Low Fuser Temperature. Probably a blown heat lamp try reseting the H code Press CLEAR, EXPOSURE MODE, CLEAR, EXPOSURE MODE. The display should go blank. Then enter 14 with the copy count keys and press START. If the machine does not turn off and back on by itself - then turn it Off and back on. See if the H code comes back. Tim

That is a document feed or scanner fault. Often times it is simply that molex connector working loose. It is the connector mounted vertically next to the main power cord on the right rear side of the machine. That bottom screw can be dificult to tighten. What I would try first is to shut the machine off, unscrew and disconnect that conntecot totally then firmly slide it in and get both the top and bottom screwss tight. Like I said, the bottom thumb screw can be hard to tighten even with a screw driver because it is a pretty soft rubber the tighteners are made out of.
If that doesnt work. go to the back and disconnect the document feed to scanner cables and reconnect. Other than that, you pretty much have to replace the feeder/scaner assembly since very very few parts are spared for that .
