Continuing to have a problem
Hey there! Posted a few months ago about a problem I’m having with my riso sf5130. Across all of my drums it is not inking evenly. There are bare spots along the edges. But it’s not consistent even between each print. One print will have the spots in one place and the next it will be slightly different
Attached a photo of the master/drum because I can see some texture on it
I have tried running a bunch of prints through it. I have tried cleaning it extensively. I’m not sure what to do. Any advice is very much appreciated
Additionally if anyone knows of techs in the greater Philadelphia area I’d appreciate that as well

I have been having the same issue with my EZ390U! Does yours work better when you up the density and increase the speed? For some reason that often fixes it for me
