    Life of feed rollers

    I am sure this has been hashed out many times, but just how long should a feed roller set last, we work on Toshiba here, and seem to see more sep. rollers getting flat-spotted, in feed sections and in RADF's also, is any one else seeing this, on other Toshiba's or any other brands?

    I don't work on Toshiba,s bur I would think that if the sep roller is getting flat spotted that there may be failure in the torgue limiter.

      We thought same thing also, changed the torque limiters, and did not see any change, changed a set just recently, due to a flat spot on sep roller, less than 100K on mach.
      It was a ES 3055.

        OEM rollers? There was a pic on here recently of an aftermarket roller gone flat within a very short period of time.......

          The 3018 DF feed tire set is frequently seen to flatten the separation on whatever DF it's on. The most important factor seems to be volume. High volume machines get better yields. The lower volume machines tend to flatten more quickly.

          The separation rollers used on the eS350 series, eS355 series, etc, also tend to flat spot in low volume locations. These separation rollers happen to come on the hubs with the tire pattern backwards. It does not help to work the rubber off of the hub and flip it over.

          The separation rollers on the eS650/850 also flat spot in low volume locations. They also are on the hubs backwards, yet flipping the rubber over actually makes it worse!

          The only constructive advice I can offer is to carry lots of spare tire kits. You'll use them. =^..^=
          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.

            We have discovered the same thing, no reason for it, some wear faster then others, hi vol. or low vol. new or old style, and I read that tech pub. about the hub being installed backwards, was not going to try the flip, we just change them when they flat spot, and right now the kits are on backorder, go figure.
