I have a Sharp MX-2610 that has intermittent E7-A0 codes. I've already replaced the LSU with driver PWB and just replaced the LSU motherboard from a spare MX-3110 (same Part#). Within 5 minutes it popped another E7-A0. I can reset using sim 14 and it may take a few days of several weeks for it to come up again, its occurred 7 times between 4/2017 and 9/2017. Other than the harness, any suggestions?
