    I have been given a Paterson Orbital Print Processor but there are no instructions with it. Using it seems straightforward but I am not sure about the amount of developer to use. The lady who gave it to me said that as it used such a small amount of chemicals she used it as a "one shot Processor". I think I read somewhenre that this type of processor will develop a print with only 55ml of developer.

    If anyone has used one of these could they advise me of how much developer they used and whether or not they used the "one shot technique".

    Many thanks for any help I can get on this.

    That’s right, 55ml is all it takes to develop prints in whatever combination will fit inside without overlapping. One 10 x 8 or four 6 x 4 prints for example. I use mine to develop both prints and 5 x 4 negatives, 4 at a time. If you intend using it for negatives it will require an easy modification to stop them sticking. It was originally supplied with three coloured chemical measuring beakers. I also use 150ml of developer for four 5 x 4 negatives. I’m fairly sure 55ml would be ok for this task, but have never had the time to try, so I ere on the side of safety. You must use the red spacer pegs if you are using it for smaller than 10 x 8 – prints or negatives. If you have the electric motor base it will be much easier, and more consistent. For other reading this, we are discussing a daylight processing tank, load it in a changing bag, snap on the lid, and it’s light-tight, just right for LF negs.

    Thank's Dave. I do have the electric motor base with it and another base I assume is for hand rotation. I also have a Jobo Duolab for print processing but the Paterson does seem easier if only a few prints are being done, also as you say it can be used with the lights on once the paper or film is loaded.

    I have the original instructions and would give them to you if you wish. I used mine till the tray developed a crack and it looks to be done for now. You really can't repair that type of plastic very well as most expoxies and glues won't hold to it. I used mine for developing film as well, but you need to sand and score the bottom so the film won't stick. Yes it can be used in daylight, but I used mine in subdued light just in case. It's a nice unit and spoken of highly by John Hick's. If you need to, you can float it in a water tempering bath. If you ever want to sell it, let me know. I could use another.
