    MP C3504 noises

    Today seems like a day for obscure '04 noises so I thought I would share my current headache.

    My 3504 makes this very fast clicking noise ONLY at the very beginning of a print/copy job and then right at the end. If I do a 10 page copy job, right when I hit "start" you will hear it as the paper begins to feed, then nothing for the rest of the job until the very end when the job is finishing up.

    I can't recreate the noise in 5-804 while turning all the motors. Seemed to me like maybe a paper feed motor but i already swapped out the paper feed motor, transport motor, and registration motor and I haven't yet but I'm about to do the PCU: Black/Image Transfer Motor (even though I get no noise while turning this in sp mode).

    Figure it may have something to do when a clutch engages at the beg/end of job.

    When I have the back open and running, the noise seems to be coming from very near the PCU: Black/Image Transfer Motor (if that's it I apologize for jumping the gun on this post) but I don't think that's it.

    For the heck of it we replaced the ITB, K PCU, and Fuser as well.

    Any guesses?

      Could be a waste toner bottle agitator, like a developer black agitator noisy...or the black toner its empty, (the empty toner bottle make more noise) and the machine do some toner load shot, toner Hopper black unit noisy

          Does it make noise in B/W or color or both?

              Did you replace the waste toner bottle?

                          Check that the waste container is not full and if it is, check the sensor.

                              Thank you all for your replies...I changed out the PCU/Image transfer motor and waste toner tank with no luck.

                              Upon further disassembly, the gear that the development solenoid touches I believe is the culprit (couldn't really tell off the SM what that part was called, maybe that is the dev. agitator that was mentioned).

                              However, whatever it is, is in the main drive assembly, and like was stated, some noises live and die with a machine. It is not the worse noise ever so I may just button her backup and keep this machine in my back pocket for a specific purpose where that noise will not be a bother. Because other than that noise, this machine is great.

                              I appreciate all the reply's so quickly, you guys are great.

                                  Infact, there Is also a bullettin that speak about possibile noise from the front agitator of developers units, (the Little box with two White plastic Gear in front of developer unit)....but never happened ti me...you can try to remove One Gear momentaring for test

                                      Agree with this. It all depends what developer assy you have. I think Ricoh realized their error and phased these out. The tapping sound is probably normal for the developer assy. Their theory was the "tapping" would prevent the dr blade from clogging and giving voids. Up to you, but I think you can just remove the gear and let it buck. I only had one doing this back when and after I figured it out, told the customer this is normal.

                                          it could be that its knocking mechanism (rtb1) is a little louder than usual, it could possibly inspect it, it doesn't seem complicated to me, or during installation, the internal mylar protection (rtb2) did not rewind well, or completely, and something touches it during rotation
