I have a sharp MX-8090 2019 with 895k that keeps getting a false jam 1st thing in the morning when the customer prints to it. When I run a 23-2 or 22-6 the jam is displayed in all caps as "FUSER". They open and close all covers and it runs fine the rest of the day. So far i've tried the fusing unit, all door switches, locktite on flywheel, PCU PWB, HL PWB, firmware is up to date, and checked the power everything checks out ok. I've called sharp for tech support but the only thing they suggested is cutting some wire ties on some of the connectors on the PCU, has anyone seen this or have any ideas?
