We have recently moved, and of course, it's not without issues. We have an older MHM SynchroPrint S, and there is a valve in the printhead arm that makes the squeegee and folder chop; I'm having a slight problem finding them, and was wondering if anyone might have a suggestion. The part number is SY3520-5LOU-M5, by SMC. I can find it with a Q at the end. Thanks in advance.
