    [Jamming] Kyocera 8353ci MPF Issue

    Hi,

    I have a Kyocera 8353ci and we have had it since day one. I am trying to run a statement sized (8.5x5.5) piece of paper through the MPF (I have done this now with this machine at least a hundred times with no issue) There is no defect to the paper, (curled edges, etc.) the settings in Microsoft Word are the same as they have always been. The paper size and type are correct on the machine.

    At first it looks and sounds normal, the machine starts to pull the paper into the MPF, it pulls it in, then you can sort of hear a noise in the machine, like the paper is catching somewhere. The machine displays an error 4109 so I open the right side of the machine and I pull the paper out. The paper is not crinkled, etc. I have tried re-running this probably twenty times tonight and the same thing is happening. Attempting to print from tray 2, now generates a jam 0512. This is the first issue we've ever run into with this thing! I clear the jam again from the right side of the printer, paper looks about half printed. Paper in tray two when you open it looks like it's catching somewhere as the papers are crinkled in tray two.

    This is a very low use machine. See attached counter screenshot. Very first issue in almost three years! At this moment paper trays one, three and four are working fine. It is just tray two and the MPF that are not working.

    I am at my wits end. If anyone has thoughts, I am open to hearing them. If you are a service company, I will happily pay you for your advice if it resolves the problem but NO I DO NOT WANT YOU TO COME ON SITE.

    Thanks to everyone in advance!

      Let's start with the simple things:

      *At low usage, those rollers could easily be dusty. I'd clean them with an orange oil based cleaner. Yes, it's oily, and the excess oil will rub off on the first few pieces of paper ... then it will feed.
      *Make sure that you are feeding the statement sized paper SEF (short edge feed)... that means that the 5 1/2" edge should be feeding into the machine. The shortest piece of paper that the machine can accept is ~8" long, so a 5 1/2" long page will guaranteed jam.
      *Try fresh paper. Moist paper can give you these jams.
      *Technically, yes you can feed statement R sized paper from tray #2, but I haven't had much success with that. Use the MP tray.
      *Are you cutting the paper yourself? Rough cuts will bind the pages together and try to pull multiple pages. Either buy the paper cut to statement R or make sure that your cuts are clean and regular.

      Start with that. =^..^=
      If you'd like a serious answer to your request:
      1) demonstrate that you've read the manual
      2) demonstrate that you made some attempt to fix it.
      3) if you're going to ask about jams include the jam code.
      4) if you're going to ask about an error code include the error code.
      5) You are the person onsite. Only you can make observations.

          If you 'help' the paper to feed with your finger, can it then successfully feed or does it stop in the same place?

          Try to watch the feed roller with camera and/or flashlight to see if it is slipping on the paper, or if it is stalling at the same time as the paper. I have some similar machines which do not like to feed via the MPTray and stall the roller due to lack of driving torque from the motor, for which there is no cure. If the feed roller is slipping, then it will need to be cleaned.

          An alternate cause of slippage might be that the MPTray isn't lifting the paper effectively to meet the feed roller... the feed roller assembly should lift slightly each time the job is attempted, lifting-failure would usually result in a C-code so this seems unlikely.

              Ok, this is a longshot from my 'random weird problems' file from an 8353ci. I have only seen it once, and not inspected other machines for this 'factory assembly misalignment':

              So this was a random jamming problem. During troubleshooting I removed the Feed Drive unit.

              Behind it, there are some couplers, one of which engaged the shaft with the fixed roll pin in the picture.

              The roll pin extends beyond the edge of the coupler and has a rough end.

              The wiring harness was installed 'too close' such that the roll pin had rubbed against and worn through the wiring.

              HOWEVER, it would only occasionally short every half rotation while driving. I cannot rememer the exact wire signal but it would throw a jam as soon as it did short.

              So pull off the Feed Drive unit and be sure that harness is routed against the left side rather than over by the rotating assembly.

                      Wow! That is an oddball occurrence. The odds off seeing something like that again are slim.

                          Greetings Everyone,

                          Thank you one and all to everyone who took time out of your day to respond to me. I sincerely appreciate it. I am indeed an end user and not a copier technician. Here's an oddity that I discovered today and I would like your input.

                          I tried printing a # 10 Envelope through the MPF and it worked fine. I also tried printing a specific label on a sheet of labels, also using the MPF and it did so perfectly with precision accuracy. So the $64,000 question: Why won't the machine print on the 8.5x5.5 paper? I have tried several different sheets of paper and still the same issue. The paper is precision cut at a local print shop. There are no rough edges, perforation lines or anything. The paper is kept at room temperature and in a cool dry area.

                          If anyone wants to chime in, I would be ever so grateful.

                              I have a few customers with this problem and I'll be honest I'm not a fan of the mpt tray on the large machines 70ppm+. What is quite funny is the slower machine 50ppm has a much bigger pickup roller and will feed nearly anything. I don't think anyone has a fix for this I'd love to know any hacks but I've seen perfectly good 250gsm jam unless you give it a helping hand pushing as it feeds.
