I am having an issue with our Uni I—it has a squeaky rider roller. I took a look at an old post, ‘Inking Roller Squeal,’ and that was helpful, but I have an additional question. The black knob at the end of the rider is loose, but when it is held in place, the squealing stops–Is there a way to tighten this? I don’t see a set screw, so does the whole rider roller have to be removed to examine the handle?
Thanks!

It should simply tighten by turning the knob clockwise. If not wrap a bit of teflon tape (plumber’s tape) on the threads of the handle.
