Troubleshooting your network connection

Ping delays and timeouts
A ping delay is displayed in ColorProof when your printer is sleeping, or if your network quality is poor.

A ping timeout is more serious and indicates that the connection to the printer is dropping intermittently off the network.

A methodical approach

Sometimes it’s necessary to troubleshoot the network connection between your PC and your printer.

This is a methodical process that involves ruling components out one by one.

Usually we recommend to start with the most basic components:

1. The Ethernet cables. Replace the cable between the printer and your network port, and between your PC and network port. It’s surprising how often a faulty Ethernet cable can cause communication issues.
2. Try using a different port. Use a different port in the wall socket. Over time, ports may become worn and interfere with the connection.
3. Your internal network. There are many components within your internal network that can interfere with the printer connection. This includes your firewall, switches and routers. You can rule out the internal network by connecting the printer directly to the PC to see if the problem still persists.
4. Printer network port. To rule out the network card in your printer as causing an issue, you can try printing via USB connection. This is only valid for users without a WT7900 or built-in SpectroProofer.
5. PC network port. The network port on your PC can be ruled out by installing a second network card.

Sometimes, a direct connection from the printer to the PC is required to rule out your network infrastructure causing interference with your printing.

The end-user is responsible for their own network and although GMG can advise on possible causes, it is not possible for us to assist with your internal configuration.
