I have recently begun to produce work on my Uni III after a long hiatus, and have run into a couple of vexing issues.
Firstly, I realized that the rear form roller was laying down ink only on the side opposite from operator. The roller will not adjust low enough on the operator side (the knob and assembly just rocks back and forth once the gear is on the rack) to ink a form. When I got the press I noticed stacks of two 2pt leads had been used to shim the form roller gear rack along its entire length (photo). As I am a complete neophyte I just assumed that this had become necessary to keep the rack level at some point. Now I’m thinking that the leads are forcing the gear too high and angling the roller. If this is the cause I can certainly pull the leads out and “see what happens” but if they are necessary evil I’m not sure what to do to keep the rack height both consistent and also low enough. I have plenty of 1 pt nylon leads I could cut into shims for instance.
Any thoughts would be greatly appreciated!
