    [Jamming] KM bizhub 420 paper problem at exit

    Hi all,
    i bought an used KM bizhub 420 in place of mine (C-6702 problem).
    Now this machine is OK, but there's a very strange issue on the exit tray (no finisher at all): the paper is bent on the center of the page, it's a very little curve, but when i send more than 10 pages at a time this is a real problem, because the printouts will not stack properly one page on top of the previous and the last page will fly down on the floor. I've searched on the service manual but there's no indication. Print quality is not affected at all, i think there is an issue, maybe on fuser section.
    Suggestion will be appreciated.

      used 420

      Did that 420 have a finisher before you bought it? When a finisher is installed three gray rubber rollers are cut off the exit roller assy.
