Network Technicians....

Crossover cable, notebook, and spare network cables.

Technically you really don't need alot of stuff. If the machine plugs into your notebook directly with the crossover cable using static IP's and works....then it's their network.

I carry an RJ45 crimper, a few RJ45 plugs, a 5 port gigabit/100/10 switch, a 5 port wired router, a 5 port hub (for running Wireshark - a switch won't work), and about 20 assorted patch cables.

About a year ago I found my favorite new tool: a cable tester with an LCD display that not only will test for continuity, but also displays which wires are open or shorted. One end has a slide-out terminator that can be placed on the far end of the cable. That was the best $30 tool I ever bought!

If you can firstly demonstrate the copier printing/scanning over a direct connection to your laptop and then via the use of Wireshark and/or a LAN cable testing tool, prove that the issue lies with the network then they essentially don't have an argument. They can disagree as much as they like it's not going to change the facts.

If they choose to disbelieve me then I'll escalate the issue to my manager with a full explanation of my findings, if they press the issue and our network specialists attend site and their contract doesn't cover it they'll end up with a hefty bill.

I can see why you are asking, I think we've all had calls to customers where the issue is related to the copier, so they want the magic copier wizards (us) to arrive and wave our magic wands and make the problem go away.
