    [Jamming] MP3350 (russian) Not lifting tray 1 high enough

    Hello all

    I have a MP3350 that will not feed the paper from tray 1. As the tray does not appear to lift high enough. Works with 20 odd sheets but any more wait in it , it fails.

    so far...... Sep Roller and Sep Pad replaced.

    In the rear of the machine.....
    Lift motor at the front checked and does not appeared cracked. Tray motor at the rear changed with tray 1 and works. Tray lift sensor in tray 1 swapped with tray 2 and works ok. Little sensor in the middle (tray detect) realigned and appears ok.
    Any ideas welcome......... have i missed something ??????????????

    When I have this fault, and the tray sensor is correctly positioned, I adjust the tray lift pressure. SP1908-5/6/7 and 8, I change the setting from -150 to 0

      Two things I look at, the lift springs and the coupler in the rising unit. If the coupler is cracked the it cant lift all the way and will cause jamming.

        Ditto, a cracked coupler is almost always the issue when this happens. As the tray lifts, the crack widens and less pressure is applied to the pick up. Not a problem with 20 sheets but the weight of a ream of paper will be. You said you checked it but you may have to remove it to confirm.

          Just an off the wall suggestion, make sure in user tools the machine is set to automatically detect paper size, if that is possible. If that isn't set correctly, some machines will not raise the paper correctly, causing misfeeds.
          If, when the machine is set to automatically detect paper size, it shows an incorrect size on the touch panel, usually there is a paper size sensor in the back of the machine that has been knocked out of place by rough handling. Usually you just pop that sensor back into its bracket, shame the rough handlers into using a bit more care and you're good to go.

            Thank you all very much for your input... really weird fault. Coupler was fine and the Sp 's did not effect it. I changed all of tray 1 mag with tray 2 yesterday. Hence why i put the fault out to the World.

            I changed the trays over and the thing started working. Put the old tray back and it started working as well.

            Conclusion....... have know idea why it started working, have worked on hundreds of these and can not see any reason why........

            thanks once again.....
            until next time....

              the sensor at the back of the tray as come loose or been broken of so the machine thinks stupid things remove the little flag from the sensor at the rear an manually set the paper size or get the useless mod and fix the sensor......................

                Have to agree with you boys, don't know the 3350, but I assume its exactly the same feed system as the older machines, and I had it happen to me for the first time the other day on a 3222. Look very carefully, the crack could be very fine and only show up when the coupler is stressed.

                  try sp's 1907 and 1908 I don't think this model has motor adjustments but if it does it's worth a shot. Also you might want to tighten lift spring if there is one and or add polywasher to feed shaft as to chimmy it up.

                    Re: MP3350 (russian) Not lifting tray 1 high enough

                    Seems like the lift spring......
                    However, I may be wrong....
                    I had this issue with MPC2551... At that time, the lift spring was slightly damaged...
                    I modified the lift spring a little, making it slightly more tension & it works...
                    Hope this helps....

                      Hello all off above.

                      I went back today as PR for the user and the machine is still working.

                      It would appear after checking every thing. It was caused more likely by the tray inner metal lifting frame. It was bowed in the middle just a little and would appear not to be lifting up higher enough just by a couple of mill, the tray paper detect sensor was just that tinny bit out off reach.

                      .

                      thread now closed.


                      thank you all for your input.

                        The problem is there is one A5 paper detecting sensor for each tray, it will be dislocated fix it in normal position. this is something funny also but i confirmed the thing.

                          fix the A5 paper detecting sensor in the behind portion of trays, its position will be dislocated

                            I cant remember for sure but isnt this the model where they originally had a single lift spring and later they added a second spring about 3 inches long that attaches to the main one. If it is i usually skip adding the secondary spring and i just take a small zip tie and stick it inside the spring down about an inch then pull it out the side and zip tie that first inch of the spring, dont usually have any issues after that.
