    Solenoid damage on ADF： MPC305 and MP301

    I have some trouble with solenoid [GX110024 (DC SOLENOID: MECHANICAL SPRING CLUTC)] on ADF for Griffin and Stella.
    Like this=>solenoid.JPG
    This solenoid is long time activated during the process of copying in duplex and eventually just damaging. And sometimes it also the BiCU is damaged.
    This is first time for me facing this problem. Do you have any experience for similar issue ?

      Hi

      We have recently had the same happen to a MP301spf. When testing the solenoid in another (known working) machine, it damaged the BCU so that the (then working) solenoid, did not function afterwards.

      We were fortunate enough to have a transit damaged machine, that we used as a donor to replace the BCU and got around it by replacing the BCU and solenoid at the same time.

      But, like i said, this is only one time so far that we came across.

          Yes I have also seen this on early models, there is a bulletin about it.


          If the customer reports jamming swap that solenoid out with a new one ASAP (not used) it becomes magnetized & sticks

              Hi everyone.

              I have several MP-301spf with the same problem, solenoid always with 24v and we think the BICU is damaged. What do you recomen to do, change BICU and solenoid?? As soon the client reports jams for this solenoid, do you recomend changing it for a new one?? You said ther is a bulletin but i cant find it on the TSRC.

              Thanks in advance!!

                  Just curious: What kind of failure is it?:

                  Open circuit? (infinite resistance)
                  Shorting between the coils? (lower resistance)
                  Coil shorting to ground? (Resistance path between coil and bracket)
                  Magnetizing? (stays actuated when current is OFF)
                  Sound damping pads getting sticky? (stay actuated when current is OFF)

                  I've seen all of these at one time or another. I would suspect coil shorting to ground if you're blowing driver circuitry on the BICU. =^..^=
                  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.

                      Do you know what the bulletin number/model is? I haven't found it on the 301/c350 page and there isn't a bulletin number next to the part in the part manual

                          In our case the coil body was visibly swollen, which makes me believe that heat was involved the caused the solenoid to deform. This makes me feel that it could be a case where the solenoid was on for a prolonged period = heat?
