The printer disconnecting from the network while no jobs in the server or printer Q.
I suspect its happened when the printer enter power save mode.
No communication available to the printer - no ping, no web communication to the printer.
Internal test pages can printed fine and the machine behave normally, no error code, except network communication.
We replace NIC network board and configuration chip (sim card on the network board). Also we replace the power board.
Its important to know that after restart to the printer the machine is back on with full communication and can print.
After another 10 - 15 min this problem comes again.
I suspect that the machine disconnecting or shut down IP connection maybe because there is no respond from the switch or gateway problem.
Usually the machine need to ignore it and keep working with IP communication but it doesn't - maybe there is new firmware which fix it?
any idea ?
