        You'll usually see: "41.03.00 UNEXPECTED PAPER SIZE" if you've got a mis-programmed paper size, and I didn't see any on your event log. =^..^=

        EDIT: Ah! There are 4 events of 41.03.00
        That will help for some of your jams. =^..^=
        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.

                What is the million copy roller?

                Did you replace just the gear or the whole swingplate?

                I like to think of the printer pushing and pulling paper. Here the registration would be pushing and the fuser a pulling. The fuser is not pulling as fast as the registration assy. Bad fuser
                probably. Double check the entry guides on the fuser

                when it does print are the pages a little blurry? Run a paper path test. Does the image shift at all up or down the page?

                Check or replace the toner just to be sure. Sometimes a shutter or hopper rail can come loose and block the paper path.

                Call the fuser vendor and tell them you suspect the fuser

                    This really sounds like the fuser sleeve isn't turning. Try getting some fuser grease and lubing. Or replace fuser.

                        HI,
                        I appreciate all the help and input.I replaced the fuser uinit, and all feeds when problem started.I replaced only gear and not the entire swing unit.

                        The jams have been a little different looking since I set all trays to 8/5 x11.this is firt times that I am getting jams with last 3 inches crumbling up.
                        THE MILLION COPY ROLLER(maybe wrong way to describe) is the tire with the gear on it in all trays except manual bypass.Should I change fuser unit again?
                        THANKS ANDY

                            Yes replace the fuser. Pretty much no doubt that's the next step. It is possible it is defective.

                            I am extremely familiar with the rebuilding of these.

                            It sounds like your million. Copy roller is the pickup roller. Does it just click on the shaft next to the other two rollers?

                            You might as well replace the transfer roller and reset the maintenance count since you did the fuser and rollers
