    300ci chirping in paper conveying section

    In attached PDF, noise is coming from motor or gear (#69/79 in pic)
    I have lubed up the gear/shaft/back of motor where clip goes with
    high-quality PTFE stuff and it went away for a bit but is back now but mostly when
    the machine has warmed up and put out several prints or so.
    It's literally a chirping that the customer really doesn't want to hear
    as the machine is in a small office.
    I isolated the noise by slightly pressing on the back of the motor to change
    rpm's and found it that way.
    Obviously since it's under MC and to save costs, should I change the gear, housing or motor?

      I conversed with a tech recently who silenced a squeak in this unit by cleaning and lubricating the impregnated bronze bushings. I think I'd try that first. =^..^=
      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.

          I think I will try that.

              It seems to have stayed away after the lube soaked for a few days
              Thank God for Teflon!

                  I had also this kind of sound on a TA300ci, I cleaned/lubricated the white plastic rollers in the lower side cover.
