I recently acquired a Universal 1 and have a couple questions related to maintenance. I have been keeping the rollers raised by raising the lever for that purpose when the press is not in use, but wasn’t sure if I also needed to raise the oscillator and a single rider fully away from the rubber rollers (as they would be for cleaning) when the press isn’t in use as well? I ask because I’m having some inking issues that recently arose (it was inking just fine before) and I’m worried that it might be that I’ve damaged or flattened the rubber rollers by not having the press in the correct position when not in use. From the manual it sounded like they just needed to be raised with the lever and I’ve never seen presses kept with the oscillator up but just wanted to make sure.
The inking issue that has recently started happening is that the rollers are inking the first part of the form more heavily than the center. I’ve checked the height of the rollers and they seem fine (though I didn’t check the height of the front and back rollers separately by taking off the first one, so maybe that is it?) It was inking beautifully before and I’m using the exact same ink, paper, and polymer plate. It’s definitely an inking issue and not a packing issue, as I can see it on the plate, and it happens at various placements on the bed and with various plates. Any thoughts about what the issue could be would be most appreciated! Could it be that the roller isn’t rotating properly over the form and therefore only inking the beginning of the form and not the rest? How do I fix this? I’ve been trying to troubleshoot it but have reached the edge of my knowledge. I have visual examples if that might be helpful in explaining.
Thanks so much!
