    5550ci grinding...

    Its from Transfer release motor. only happens on power up/down. It will start no problem, but its like the "stop" signal arrives a half second late and the motor spinning against dead stop creating the grind noise.

    I was troubleshooting a noise around the fuser, touched the relay board to say the least(yc14 location)... And this happened. Initially i thought was the fuser/fuser drive components, but after afternoon of struggling i narrow it to Transfer Release Motor.

    and I have absolutely no idea what i touched to mess it up..



    any ideas?

    I mean, i could change out this particular motor, that board, the "L" ribbon cable(which i seriously hope not), the big bundle of wire harness including the connector... I really wish the timing chart and theory of operation of most of these sub componet stuff is still in the manual...

    any way to reset the timing?



    /and apparently i scraped my pinky against the baremetal frame in the chaos not knowing, there was ceremony, there was sacrificial blood. But still nothing ...

      we have replaced that motor before, for noise.

          so the story is, during the mess of things, i forgot a ribbon cable (the one that goes downward). So that resulted in the press release motor spinning against dead components, skipped gears and missed its home position (cam-ed).

          So i took another assembly, swap it, all is well. Its not a self adjusting component one would think it is.

          phew~

              If you dig into it there is a gear reduction that draws back the secondary transfer at the conclusion of each print job. The plastic housing has a post molded into it, which breaks off. I've replaced that housing a couple of times. =^..^=
              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.
