    [Misc] Rust on Fusing gears mpc 7500 6000 6501 7501

    Does anybody have a solution for getting rust build up on the fusing gears of the MPC 7500's? Besides replacing them? It has been taking out the pressure roller bearings on my machines.

      Check for clean filters and full running fan, without good circulation the moisture will take its toll.

          X2, especially the filters. we've discovered that keeping them clean helps with several issues.

              I use the SS silicone oil from 1224/3224 to lube the gear. it works fine and it can stand the heat.
              Nothing is impossible for them who should not do it.

                      A liberal coating of Ricoh MT-78 grease, part number 5447 9078 (if you can still get it) It appears to be graphite based, also helps keep them quiet.
                      At least 50% of IT is a solution looking for a problem.
