    RDF-D1 Trivia?

    What is the purpose/function of the Jump Lever (part numberFC2-2907-000, fig P16, item 83)?

    Do not know the answer, but several of us noticed it does not have any obvious function.

      Obviously its only on the newer version. i have a book and it doesn't even go there. looked up on Canon site and there is one. i looked on a machine here, there isn't one. the stepped screw, one each side prevents rdf assy from opening any further when it reaches its limit, so it wont go beyond. Whatever the lever is, or does, is beyond me. I don't have one to look at. So humor us.
      Maybe it was put there to do just that, humor us.

          I am not a Canon tech, but, why not disconnect the sensor and see what it does wrong?

              I looked at the diagram...it also has a torsion spring on it...looks pretty useless..maybe keeps tension on document tray mount brackets so that drive belt doesn't jump when tray leaves position..diagram only shows one at rear...no idea

                  You've got my curiosity. Can you post a photo? Or maybe just the parts diagram exploded view? I don't have any RDF-D1s around to look at, but I did work on them for 6 years.
                  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.

                      No sensor - it just has the spring and attaches to the side of the document tray. It piviots as the tray goes down - but does not touch anything else (other than the bottom - and that does not have a stop/sensor). BTW: spring is too light to be a "return" assist.

                      I did take pictures and will post them after I get home as I do not have my data cable here.

                      First shot at adding the photo.

                              Left feed stopper arm solenoid, maybe....

                              I'm thinking that this is the stopper arm solenoid. If I'm correct, if you unplug this solenoid the left side stoppers will not lower, and you'll get jams left feed, but not right feed.

                                  As shown in the picture - it is not a solenoid. Just a white plastic arm with a light spring attached to the side of the tray arm. I suspect it is suppose to "assist" the arm in "rebounding" the platform - just seems like a really light spring for that.

                                  Oh well, I really appreciate all the efforts but this may have to go in the same box as where Jimmy is buried.
