Printer started giving Error 79 Turn Off then On error about 6 weeks ago, continuously rebooting itself. I updated the firmware and it was fine for 4 weeks, then started again. Updated firmware again (same version), no improvement. Noticed that it only had a problem when connecting to the network, so I turned the wireless on the printer off and connected via ethernet cable to the router. That worked fine for almost two weeks, then in the middle of a print job it crashed. Disconnect the network cable, it's fine, reconnect the cable it crashes. I cleared print queues on all computers, updated firmware again (same version), disconnected and reconnected power. It only gets the error immediately after it connects to the network.
