We are trying to solve a problem with a Martin Yale 1812 folding machine that stops after 4-10 pages. If we press the run button again it will do a few more. In test mode it will fold the entire batch of 50 or more with no issue. We called Martin Yale and received a new PC power board which we installed and still have the same issue. Also in test mode the sensors all check out as good. I am open to any suggestions or insight.
