    [Misc] Help cleaning the inside of a color drum?

    Hi all, the drums for my gr3770 & 3750 were sitting in a garage for 10+ years. As I am able to buy new inks and install them in the drums, I am coming across a few that appear to have clogged tubes where the ink bottle inserts. I am also getting low ink coverage with these particular drums. I intend to clean the screens with a solvent soaked rag but am thinking it may need more than that. Below is a pic. Have any of you ever attempted to take apart a drum and clean the inside mechanics?

    What does the ink bead look like in the problem drums?

      Doesn't answer all of your questions but I used De-Solv-It citrus solvent to clean the exterior of a dried out GR3750 drum and screen. Sprayed down some paper shop towels with it and let it soak. De-Solv-It Citrus Solution, Organic and Biodegradable
