    Sharp AR-507 Jam

    Would someone be able to tell me what the jam code PPD2_NT1 is for?
    I think it could be the registration sensor, since by the manual it says that is PPD2.
    This one is flaky, it will work sometimes and sometimes not.
    Could it be just dirty (under DV unit) or is it a known problem, or something else I am missing.
    Thanks everyone.

    Hi Cameron,

    Always look at the whole code, not just the first part.
    Your jam code is saying that PPD2 sensor has not been reached when feeding from Tray1. You will probably find that tray1 paper feed rollers are worn/dirty, paper feed clutches are not working/timing correctly or less likely that something is causing misfeed timing fom tray1.
    Always do a continuous copy test from another tray or the bypass tray to confirm that the tray listed in the jam code is the only problem.
    The code does not always mean that the problem is with the PPD2 sensor, but the tray that paper is being fed from. If the PPD2 sensor test is working in simulation OK, I'd be checking that tray or feed unit.

      Hi there, N codes mean "not reached, whereas "S" codes tend to indicate "remaining" jams. You will need to remove the registration assembly. The front frame side is easy enough, but the rear frame side is held in by a self-tapping screw, which may mean having to remove the drive clutch unit (I always left it off when re-installing!).
      The PPD2 switch will be either dusty, or the arm worn enough to cause intermittent jams. The 2 rubber rollers in this unit should have a tread on them. This can also be the cause if worn. I used to reman Sharp Cougar range m/cs, and this feed unit is almost the same on the AR 285, 336 505, 507 etc.
      I hope this helps you.
      Good hunting!

        Here are a few suggestions:

        Misfeeds (jam code TRAY1, PPD1_ST1, PPD2_NT1) from tray #1, no paper is found. Recent toner spill on AR-250, 335. (Tray #1 jam, upper vertical path jam, pre-registration jam). Toner is spilled on the tray #1 feed tires. Clean up the toner spill. Clean or replace the tray #1 PF tires (NROLR1219FCZZ, NROLR1218FCZZ, NROLR1229FCZZ).

        Misfeeds (jam code PPD2_NT1, PPD2_NT2, PPD2_PRE) duplex only on AR-287. Defective duplex clutches. Replace duplex clutches (PCLC-0290FCZZ, PCLC-0291FCZZ).

        Misfeeds (jam code PPD2_NT1, PPD2_ST1, DUP) Z-folds 2nd side of duplex at the registration roller, or overlaps two pages at the registration roller. Duplex only on AR-287, AR-336. Defective duplex clutches. Replace duplex clutches (PCLC-0290FCZZ, PCLC-0291FCZZ).

        I can't improve on the previous posts. =^..^=
        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.

          Thanks everyone for the replys.
          I pulled out the feed units yesterday and cleaned the rollers and 1-ways, the rollers are new but previous company had oiled the 1-ways (a no-no).
          I did not try another tray (forgot). We don't normally work on Sharps but I do have a manual for this one.
          When it codes the paper has not reached the sensor, or just reached it, and maybe one in the fuser. Just being crazy.
          I will try cleaning the sensor first and run other trays to see what happens.

          Thanks

            Forgot to say that the machine was just moved to this location (donated). So it could have toner down in the sensors.

            Thanks

              You may find the drive clutches are causing the problem, but there may be wear on the vertical transport roller or I have had a dry joint on the small pcb on the vertical transport roller.
              On a lighter note, I just like to help people, rather than lecture them.

                A couple of other issues to be looking for on the old AR-507's...depending on number of copies on the machine, that vertical transport unit could be getting ready to wear out, replacment is the best bet, 5 or 6 clutches in that beast, and not fun to take apart, getting it out aint too bad.
                On feed rollers, I have seen a set go 400K or more copies, I would change them at about 350K or so, it will try to feed from the cass 3 times before it shows a jam, thats always is a good indication of worn rollers.
                Dont know what it was the cougars that ended with "7" seem to have more issues then the ones that did not.

                  Thanks everyone.
                  I just got back from there, when they moved the machine the dumped some toner on the sensor, after cleaning it real good the machine works great.
                  Thanks for all the advise.
