Hello - working on one of my favorite head scratchers with a 110. Machine threw errors F4X01, F4X02, and F4x06 - all related to homing out intrack and crosstrack guides. I feel like it's an intialization issue, but it's not software and I took a whole set of logic/CMC boards from a working finisher same style and I get the same errors. We've tried swapping most every board in the thing, wasn't sure if anybody might have a tip or a fresh idea on it. It also seems to think the intrack paper level sensor is blocked. I'm about ready to push it aside and work on a different unit, hopefully have better luck. Thanks for looking at my post, have a good day
