Xerox DC 440. Powers up and comes to ready. However, it does nothing after pressing the start button. When attempting to enter diagnostics, a job is pending (allegedly). When trying to delete it to proceed, nothing further happens. No jobs are in the queue. Techs have replaced UI(idiots) and the ESS. All systems turn on heat up normally. Can't get an error code off of it. Helps
? Also, the glass has been cleaned, and we blew off the connectors...
