I have been having issues with a Document Feeder jamming intermittently on an E-Studio 452, using the MR-3018 doc feeder. I have flashed the machine, because this started after replacing the hard drive. I'd hate to replace a board, but we have tried replacing the entire document feeder with no luck. I don't remember the Jam code exactly, but I did check the input to make sure the sensors worked fine. The input sensor is 03-7 (fax on) sensor G, which is the exit sensor according to the manual. My last resort is to replace the logic board, but if anyone has run across this problem or has some advice, I would gladly appreciate it.
