    As I Recall Dispersant was Isopar M. It i still available under that name if you look hard enough.

    If all else fails read the Service Manual!

    If that fails, meet me at the pub and we will discuss it.

      I started out working on Olivetti and IBM Typewriters. The first copier I worked on was the Canon PC25 around 1990. Also worked on some Mita machines around that time as well.

        this post is awesome. my dad was a dealer in 1980 I remember the minolta ep 101 and all the liquid machines that were horrible but they worked.. lol
        he spilled on a customer floor and I always heard that story. I personally have worked on the ep 450z a lot or the ep 300 when I started in 1992 we stil had some left
        maybe it was a ep 310 but that was long ago

            SF-301 I think. Blue color. There was another one I think was a 330?
            I remember I had a tech ask me if it was ok to adjust the pressure spring if he had wrinkles.
            I said whatever you do, DON'T adjust the pressure springs.
            Glad those things disappeared quickly!

                Started around 2000 working for a Canon dealer. I can't remember what I had for breakfast, let alone 25 years ago, so the models escape me. I only remember they were all analogue machines that had the one big belt for the document feeder that dragged the pages over the platen glass and toner was dumped from a bottle into the hopper and the finisher had a worm screw driving individual output bins.

                We also had a colour machine (I think) that had a transfer drum made from two clear plastic sheets wrapped around a cylinder that paper adhered to statically. I remember I hated working on it, and it was down at least once a day with jams.
                No, I will not send you Manuals, Software or your own little repair Genie to fix all your problems for you.

                  well i am still young compared to some lol i didnt come along until 2010. but i started out a kyocera dealership. i worked on fs1810, km 3060, and others along that time frame. and i have worked on a good many since. no longer with kyocera, but still get stuck on one from time to time. now i mostly deal with lexmarks, ricohs, hps, and brothers. oh, joy the fun i don't have lol. i guess i will give an example of how young i am. i once was sent to work on one. dont remember the make, nor model. but the top slide across for making copies. similar to the photo in the first post here. and it opened like a clam shell. i had never seen one before. thought there was a hair stuck inside the machine. but i couldn't get it out... uh yeah it was the corona wire that had broken. i had never seen nor even heard of it before. lol

                    I remember once, I thought I wasn't going to make it back to the office, dead of winter. Took two bottle of dispersant and poured it in the gas tank to get me
                    back to the office (company provided van). I think it was 1982 or so?
