Right before the holidays I was finishing up a print job and noticed the the rollers didn’t want to turn with each other anymore. I thought it was the ink drying as a result of the heater blowing close to the press area and didn’t think about it again. After being off for a few weeks, we inked up the press today and are having the same issue. It isn’t as bad, but the rollers are hesitating in the same spots as the move against each other. I have taken off the front form roller to try and identify where the problem is coming from. Everything runs smoothly when the front roller is not there. Everything also seems to run smoothly when there is no ink on the press. I thought maybe my ink was old, so we cleaned the press and put on our freshest can of ink (opened 1 month ago), but it still is an issue.
I tried to switch out the front roller to an old one and the problem still persisted. I have oiled everything and checked to make sure all of the screws are secure.
Per Fritz’s recommendation, I am going to remove the crescent from the ink drum and make sure the stem is well lubricated. I will let you know if that fixes it.
In the mean time, I would love to hear other thoughts. Here is a video: https://vimeo.com/84153721
