Uni I power carriage trip issue

Hello Vanderblog,

This is my first post, and hopefully will be resolved simply. Thank you in advance for any and all feedback.

My press, when set to auto cycle, does not engage the trip mechanism on the return of the carriage. The image will print ever so slightly on the tympan (depending on my packing depth).  The issue seems to be that the carriage does not travel far enough back to pass over and clear the rear trip wedge. The mystery is that when set to manual, it does just fine and there is no problem.

My press does have a repositionable gripper opener cam, and the position of this does not change the problem. My press does not have adjustable carriage bumpers.

I’m not sure what is happening. Any insight will be helpful!

    Try adjusting the limit switch cams—the rails that hang below the carriage and contact the limit switches on the backside of the press. But note the original position before adjusting.
