    I don't think so. Could be wrong.

      Once pi holes start to develop, the drum is beyond recovery. Any attempt to do so could result in toxic fumes being released.

        Drums from China are soooo cheap...
        😀
        ....and they all come anyway from China.

        BTW, rebuilding is very easy.

          Back in the old days on Mita, with selenium tellurium drums that used a cleaning corona unit rather than a cleaning blade, we would use a very small amounts of enamel nail polish to fill low spots (dots). It worked for two reasons: 1) there was no cleaning blade, so no mechanical cleaning issue, and 2) it left a very small white dot uncharged. On analog technology it leaves a nearly invisible white flaw in the image.

          I experimented on a few drums in the early 90's. It will not work on any drum that uses a cleaning blade for two reasons: 1) It leaves a teardrop shaped area that does not clean, damages the cleaning blade, and eventually becomes a line, 2) It leaves a very small area uncharged. On digital technology that shows as a black area on the image.

          Your only recourse is to replace the drum.
          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.

            Some have experimented with UV-curable resins or lacquers used for optical discs, but the challenge is maintaining the drum’s electrostatic properties.
