Title says it all. My finisher has been dropping out of connection on the press, causing a fault that forces me to restart. Sometimes when I restart it doesn't come up in the boot sequencer. Have replaced ethernet cable leading to the finisher, but that fixed the problem only temporarily.
had this with my stacker, a LONG time ago. but it only turned out to be the electrical plug was backed out slightly...... turn of igen reseat that plug. any other non communicating module problems have been boards.
