This IM6020 initially had no lift on Tray2 alone; Trays 2 and 3 lift motors were swapped and connectors checked, and then Trays 1, 2, 3 and 4 no longer lifted. All trays are recognized throught he set switch, we get a change in state (H and L) when trays are inserted/removed in I/O mode. We have 24volts at connector 237, but no 24volts at the on-board fuses on the Printer Control Board. We've swapped Printer Control, Overall Control, and DCPS1 - no change in state. Load check produces 0 motion on lift motors. We're currently attempting to swap the wire harness for all four lift motors.
Any thoughts??
