I have a couple of Lexmark Optra T612 printers and I replaced a sheet arm assembly on the top tray. When I turn the printer on now I get the following message: Cover Open 78.93 91FD Do you have any suggestions? The cover is not open and everything else seems to be fine. Thank you so much for your help!
