Follow the steps below to guide you through waking up the printer.
Press the green or Start button on the control panel. If the printer wakes up, yet is still unreachable over the network, proceed with Step 2.
Power off the printer and power it back on. Observe whether the printer connects back to the network or remains inaccessible.
If the issue persists, proceed with the steps below.
Disable network speed renegotiation, which gets activated when the device enters sleep mode. There are three possible methods to do this:
Method 1: VCC.zip file
Note: This method is preferred for larger printer fleets. This requires printer firmware LW63.##.P746 or later.
The VCC key nvForceGigE value will be Auto if it is On (Enabled) and Off it it is disabled.
Method 2: Config Menu
Power off the device.
While holding down the 2 and 6 buttons, poweron the device.
Scroll down to Ethernet Renegotiation and tap the arrow.
To disable Ethernet Renegotiation change the value to "Off", to enable Ethernet Renegotiation change the value to "On".
Method 3: .npa file
Next, and in the order listed....
Download both files:
Send the setOffline.npa file to the printer.
Send nv_GigE_disable.npa. to the printer.
The .npa file can be sent to the printer in the same fashion as a .fls firmware file.
