    Pickup rollers as feed/dfp

    Hello all! We've been experimenting with different roller combinations and it got me thinking. One of our customers is doing about 2mil a year on their 958. They absolutely should have gotten a production machine, and they did, but their program could not communicate paper density so it would constantly jam. Even the A64J564101 and AA2J560000 combo seems to last less than a month before they need to remove their LCT and give us a call.

    From my understanding the main reason A5C1562200 are only used for pickups is because of excessive noise when used as anything else, right? Has anyone experimented with using them as pickup/feed/sep? These guys are blasting music during the work day so I imagine they would never notice a difference, but I don't want to use them as a test with how high volume they are.

      I've never tried using the ribbed rollers in all three positions, myself. Since the ribbed pickup rollers are softer, I would suspect that they would go flat quicker in the separation position. That's the one that seem to fail first.

      I got the best results using the original A5C1 5622 00 & (2) AJ00 5636 00. I've found that the hubs with built-in clips tend to come unclipped. I've seen up to 560K from an LCT or 350K from tray #3 or #4 at the top end. Conversely, you can get as little as 180K if the page separation is set too lightly (flat spots), or if the separation mounting bracket gets bent (rollers don't meet parallel, wearing the rollers conical).

      Also watch for worn conveyance rollers in the LU-303 LCT at about 1M feeds (A03N 7002 01). You'll see "Incorrect paper size loaded." and misfeeds J20-02, 15-01, 17-20, 99-01 from the external LCF, LU-303. When new those conveyance rollers measure 74mm circumference. When the jamming starts they'll be at 68.5mm circumference. The "paper ruler" trick works here.

      You might try the improved i-series rollers:
      Pickup A5C1 5622 00
      Feed (TM53 Urethane, Red) A64J 5641 01
      Separation (TM61 Urethane, Blue) AA2J 5600 00
      They have the built in clips, so you may want to transfer them to the old hubs.
      (Oops, you already tried that ...)

      I'll be curious about your observations. =^..^=
      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.

          Agree with BC you need hard rollers on separation. Those for I series KM told are improved but I haven't machine with lots of clicks to find out. Even you get 300+k from regular rollers set my theory is on 600k oneways and torque limiter are about to fail thus better replace them as a set plus rollers.
          On a side note:
          Good question young brother keep thinking
          A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.
          Blessed are they who can laugh at themselves, for they shall never cease to be amused.

              This is a little counter-intuitive, but you might give it a try:

              Kyocera rollers which typically last very poorly in every MFP, but especially poorly in Konicas ... well, Kyocera came out with an orange urethane feed & separation roller.
              You might have to switch hubs:

              Feed: 302V694130
              Separation: 302V694140

              (if you're switching hubs, the rubber is probably identical).

              Again, I'll be interested in your observations. =^..^=
