Follow the steps below to guide you through waking up the printer.

  2. Power off the printer and power it back on. Observe whether the printer connects back to the network or remains inaccessible.

    • setOffline.npa
    • nv_GigE_disable.npa


The device dropping off the network, or losing network connectivity, in certain customer environments is caused by the printer renegotiating its IP address when entering or exiting sleep mode. This speed renegotiation is necessary for Blue Angel compliance. Please be aware that disabling ethernet renegotiation will take the device out of Blue Angel compliance.


Disable network speed renegotiation, which gets activated when the device enters sleep mode. There are three possible methods to do this:
