    The Royals were good machines, we had a lot of 115 and 122's out, full pm's every 20,000, that was good back in 1984. now it's pm's every 600,000

    The Konica 1803 was the first Konica Royal I was trained on, but I worked on a lot of the 115's and 122's. Prior to that, I'd been a Minotla/Mita guy....

    In the late 80's I worked a far flung territory, on the Olympic peninsula in Washington state. Konica was on the State contract, and we had a copier at the Makah tribal center in Neah Bay. That was an all day drive, for one service call, out at the end of the Earth. Sometimes you needed to get creative to avoid a follow up. ;-)

    Our machines use the same PCU and I did something like that but instead of using sealant, i used strips from a 3M dish washing foam. Works great. Does not cause bulging as the foam flattens when i screw the cover back.

    You can also buy the dev unit bushings (non oem) from sellers. This will add more life to your rebuilds and keep dev out of the gears for a longer period of time.

    xcopier, I'm looking around from some foam I could use. I just happened to have the RTV, a buddy of mine who used to rebuild toner carts uses this.

    Polarbear, I'll have to look for those bushings. I agree, new bushings would be very nice....

    Robinh I bought them from a local supplier who sourced them from India (probably via Alibaba.com). They did have minimum quantities though- was around 100 units.
