    6052ci Noise when the fuser motor runs on high speed

    I have a 6052ci that makes a loud noise when the fuser motor goes to high speed. I can run the fuser motor in U030, but that only runs in low speed. So no noise.

    I have cleaned and lubed the fuser motor assy and cleaned and lubed the exit section. Didn't seem to help.

    If I touch the area where I have pointed the camera, I can feel a vibration.

    If you have heard this and have a solution, please let me know.

    Thanks for the help in advance.

      This is how I test for bad fuser bearings. Tap the fuser unit on the counter top (preferably onto paper) ... you'll get an orange cloud of ferric oxide (rust). =^..^=
      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.

          And if you see that orange dust/grease replace the fuser. It WILL start giving 6600 errors sooner rather than later.

              Are the bearings that fail and make the dust easily accessible for dropping some lucubration on them. Think it would help?

                  Not easily accessible, and it's the crappy metal shafts that wear out, not the hardened bearing surfaces. These fusers have been modified at least a dozen times ... one of these days they'll get around to engineering more durable shafts.

                  The good news is, that if you're a dealer you can get warranty ... again, and again, and again. =^..^=

                      Silent mode, motion sensor off, power save as low as Customer can tolerate. Do them three things fuser lasts a very long time on 52 53 54 series. I've had fuser drive units give out before the fuser dies.

                          Thanks fishleg.

                          Silent mode and power save as low as Customer can tolerate. I do that.

                          However, I haven't thought to change motion sensor off.

                          How is that done and how does it affect the fuser?

                              We dont use silent mode any more. We do 346 fuser mode off.

                                      Thanks blackcat. I have added that to my setup.

                                          The short answer is, the bearings are made in China.

                                              Re: 6052ci Noise when the fuser motor runs on high speed

                                              It's actually not so much the bearings or their quality, but is the way that the bearings are implemented. the shaft sits in the bearing by a "press-fit" , possibly using temperature shock to put the part together. The problem with this is, the shaft and bearing are subjected to really extreme temperature swings throughout normal operation which challenges that friction-fit of the bearing on the shaft. eventually either the bearing works itself loose from the shaft or else the bearing grease begins to age, and the extra resistance "helps" to work the bearing loose from the shaft and it begins to spin on the shaft.

                                              When you look for the source of the "dust" that comes out of the fuser, teardown will reveal that the shaft material is worn-down at the bearing inner-race and turned to dust/rust. The bearing will not feel great by itself, but it still technically rotates without a lot of extra resistance .

                                              The bearing on these fusers SHOULD be mounted with either a flat-sided or otherwise keyed shaft, or else it should mount on a taper so that pressure can be maintained with the use of a threaded nut.

                                                  As i had written in another post, sometimes U000 reports or specific values are important for further analysing:
                                                  How to analyse if it will happen or not depended to the kind of usage onside, take a look for U167.
                                                  U167.JPG
                                                  Now you can decide if you has to change U346 or if you activate silent mode.

                                                  (It a good sample, coming from our show room system with very bad values)
