Acquired one of these last week - I've been looking for a slot processor for my tiny bathroom/darkroom for a while now. The Jobo is bigger than I expected, I think it's based on a 16x12 tray, for some reason I was thinking it was 10x8. Anyway, it just fits! Has anyone used one of these? Mine came without any instructions, so I only have the picture on the box to go by. It looks pretty straightforward, but any tips would be appreciated, particularly with regard to the paper clip/holder. I'll add some photos when I set it up for use.
