Troubleshooting
Network Hardware
Connections
Be sure that the NIC has properly selected the connector type
that you are using. The connector type is listed on the status/
configuration report: 10BaseT or Thinnet.
For Thinnet, check that network connector is plugged
into the BNC connector on the NIC. If the printer is at the
end of a run, ensure that a 50-ohm terminator is installed.
For 10BaseT, check that the network connector is plugged
into the RJ connector on the NIC.
Try another cable to make sure you do not have a bad
cable.
If you are using a 10BaseT concentrator hub that does not
support the link signal, use Manual Ethernet Port selection
instead of the factory default of Automatic Ethernet Port
selection.
To use Manual Ethernet Port Selection, you change Jumper 4
on the NIC:
1. Power down the printer and remove the NIC.
2. Locate the jumper and change its position from the AU
position to the MAN position. In the MAN position, the
jumper covers the center pin of the jumper and the pin
nearest the MAN designation.
3. Install the NIC.
