    [CQ] OPC drums

    hi,

    Putting this in the Canon Forum but I guess could relate to any OPC drum. Has anyone successfully repaired little nicks/pits in the drums surface? Some techs say you can repair very small nicks/pits with nail varnish, but i have never found this to work. I put in a brand new irc2380 drum in today and noticed a little speck of cyan on the copies, took out the drum and very small pit mark on the surface. Tried wiping it away but ended up worse and taking off the drum surface. Has anyone got any tried and tested method for these little marks?

    tks

      Negative on that. This worked on Mita DC-122 and DC-131 only because there is no drum cleaning blade. These machines used cleaning coronas. Any surface irregularities of the drum will not clean properly with a cleaning blade.

      There are still a few manufacturers that make machines without cleaning blades; Brother and Kip. =^..^=
      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.

          Take this with a grain of salt please, as I haven't officially worked on Canon equipment for a long time.

          But blackcat4866's right, nail varnish only works when there isn't a cleaning blade. I haven't seen that work since the 80's when the 3M 360 series used a rotating brush to clean the drum. And even then that was only a temporary fix, as the nail varnish covered area would produce blank spots on the copies.

          If I understand the pits you speak of correctly, you might want to consider that they may not actually be pits. In the time I've worked on copiers and mfds, I can't remember seeing pits in new drums from either OEM sources or some of the aftermarket stuff that the mothership would temporarily try out every once in a while (well, except for when the drum was handled poorly, but there were obvious dents in the drums then though). With that in mind, you may want to see if there is something that is contaminating the drum surface if time permits. Your initial description even sounds a little like that was the case, as when you wiped the drum off you may have just been smearing things around.

          Well, I hope that helps, and if not I'm sorry for wasting your time.

                  The part with the paper is relative since the drums of all color MFP's and several Mono machines are not coming into direct contact with paper anymore but with a transfer medium.

                  Still would love to know more about transfer belts and their properties though....

                      Damaged transferbelts can cause damage on the drum also, I assume..
