    This is a common problem discussed here before. The Clutch pins (MR 110) that slides in the end of the roller cores is worn short and need to be replaced. NA Graphics has these. Best to call (970) 387-0212 or email: info@nagraph.com

    It is also likely that the brass clutch plate that the pins contact is worn at the point the pins contact and needs to be brazed. For more on this previous discussions:
