One of our SP-15 presses at UAFS has an oscillating cylinder that is slowing way down shortly after being inked. It doesn’t seem to matter what kind of ink (ie, stiff or loose); it’s as though the ink is too thick. This machine has had a motor replacement (posted a few years back on this forum) which included a control switch for speed. I have tried upping the speed a bit, but it does not seem to help. So it would seem that inking the rollers increases the “load” on the motor, and that is slowing it down. I’m wondering if we were given the wrong type of motor?
