    Is the separation roller in feeders supposed to spin backwards?

    I have a couple of C3003 feeders I was having issues with (double feeding). I have always believed that the separation roller wants to spin backwards unless there is friction from the feed roller or just one sheet of paper going through, but on the two I have, when I spin the gear that sep roller is on it doesn't move the sep roller. Am I losing my mind. (it is possible)

    If your having Double sheet feeding replace all the feed tires? Usually you can't test, only cleaning, if cleaning has not fixed replace them. Also one way bearing or torque converter

      Yup, I changed everything. One is double feeding, the other had the problem with the optical sensor, but neither of them appear to drive the separation roller.

      The one with the sensor problem doesn't double feed though. It "appears" to work normally.

        With the 3 tire system, the separation should follow the feed without paper or with 1 sheet. With 2 or more sheets it will stand still or reverse.

        I don't know about this DF, but most of the newer ones have a slotted adjustment for the separation pressure. Tightening the spring makes the separation follow more, loosening the spring makes it follow less. =^..^=
        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.

          Sounds to me like you have a bad torque limiter.

            I swapped that out though. When I turn the gear the shaft is attached to, the shaft does not spin in either direction. Maybe I should make a video...

              You may have a bad shaft reverse roller sub-assy D6831632 or gear reverse roller D6831635. Most likely the single D on the gear has gotten rounded out.

                New firmware suppresses the reverse rotation when motor stops causing j63 jamming.

Usually you can't test (Usually you can test, it's called ADF freerun), only cleaning, if cleaning has not fixed replace them. Also one way bearing or torque converter (converter? we're not working on Cars here, the correct term is "Torque Limiter", Two completely different things).

                    Actually he is an American citizen from Florida. According to his profile he has been in this business almost as long as I have. His biggest problem is that he is a liberal. If you have a problem with him, either use Private Messaging or use one of the political posts he follows in Rants Raves and Everything Else.

                      You're right slim. I saw he was from Florida, but his bad grammar/spelling/calling parts by wrong names/etc. on almost every post made me think that his first language isn't English. Most "IT Techs/ Serv. Techs" that I've worked with or talked to (such as yourself slimslob), are usually very literate, and can convey a message clearly and correctly. Sorry to have gotten off track from the post.

                          On some of the newer models you have to go into Special Service mode to gain access to free run. Kind of dumb in my opinion, do not know why they felt they had to move that.

                            A number of models back Ricoh moved a number of highly useful SPs into Special SP and Factory SP.
