    Explain that

    I have a high speed paper folder that I service for the base print shop. A few months ago I replace everything to do with the feed separation. They spent hundreds. They called with an error. It means the separation needs adjusting. I try and try, but it either pulls extra sheets or not at all. Finally I get a ream of raw paper and it tri-folds the ream in about 2 minutes with no issue. I look at the stock they are trying to fold and it has a nice sheen to it. They switched paper a few months ago.

    "It's your paper" I exclaim.

    The customer points to a cardboard box and ask how it was able to fold the 7,500 pamphlets in the box.


    DOH!!!

    On their production machines, Ricoh recommends using the older dark gray type feed rollers when using glossy or slick surface paper. The newer composition roller will quickly lose their grip on slick paper. You may be having a similar problem.

      It's magic.
      I know I should be ashamed of myself. Strangely though, I am not.

        Ah, the stand alone finisher spirits are a fickle bunch, I know them well. I have learned that most of the time they will leave you alone. Every once in a while they will cause great bouts of rending of clothes and gnashing of teeth, though.
        I don't know if this will help as it sounds like you've already dealt with it, but if that machine uses a feed roller/sep pad, I'd check drive for the feed roller. On the machines I work on with that feed system there is a belt that will slip after a while, causing the feed roller to stall if there is standard pressure between the roller and the sep pad, and the roller will only turn when there is too little pressure to separate the sheets.

          I think we've all had that experience at one time or another, copiers too.

            Machine is a Martin Yale 2045. Drive is a giant gear with a spring clutch and solenoid. I replaced it a year ago. I am going to assume the roller has dust and loose ink embedded in it and am going back with some heavy duty cleaner to give it a good scrubbing.

              MY separation SUCKS! It's a non-stop headache and it constantly needs to be adjusted to make it work right and not double feed. The newer machines are even worse than the older ones. I'm wrestling with a 1700 right now myself.

                Drat, that's almost nothing like the MBM equipment I've seen. Sorry for the waste of time.

                  We have a church customer that has a Martin-Yale 2051....much like the 2045 you mention above!...we have put multiple spring clutches on and have dealt with double and mis-feeding...everytime the machine comes in our shop, I grimace!...it's a finicky piece of kit that in this day and age, shouldn't be so damn flaky when it comes to maintaining proper adjustments!

                  and yes,

                  I DID RTFM!

                    Re: Explain that

                    I went back, ran another ream of raw paper, no issue. Took out my new cleaner and a tooth brush. I scrubbed and scrubbed. Ran about 100 to 120 of the problem papers before jamming. This was an improvement. Puts me back to thinking the rollers are impacted with ink and fiber. I gave up on scrubbing and ordered 2 more rollers. When I take this one off, I will try to soak it in something.

                      I don't know this machine but I feel for your frustration with it.

                      You may like to try a MacGuyer bandaid as a last attempt :
                      Remove the feed rollers off the shaft a run few layers of insulation tape around the metal shaft, then refit the feed rollers back on the modified shaft. The bandaid modification will increase the feed roller diameter an increase the feed and separation timing. I've done this with a couple of machines over the years to increase the life of the machine; when the customer refuses to buy parts or replace the machine.

                      You may like to post a couple of images to the forum,somebody may pickup on something for you to try.

                          Re: Explain that

                          I installed a new roller and adjusted the retard pad until I got it to work. A good 30 minutes of moving the adjustment screw a bit, run some and adjust it some more. I left it working.

                          A few days ago I got another explain that. A church school has a Bizhub 42 and had poor print quality. They put about 150,000 a year on this thing. Had 319,000 on it. I changed the drum and developer that had gone almost 200,000. Regular prints were fine. Thick stock that they print report cards on looked bad. I ask if they were programming it for thick stock. They looked confused. I showed them how and then the cards looked perfect.

                          "We never had to do that before"

                          "Don't care. The operators manual says you are supposed to. When in doubt, RTFM" I actually didn't say the last part out loud, it is a church school, but I was thinking it real loud.
