Toshiba e4555c IP address issue

[blackcat4866]

I should have clarified "no other devices", there are no other printers,scanners,copiers,mfc on the network.

It doesn't have to be a printer, scanner, copier, or MFC to be a duplicate IP. In my experience lately it's been either a wireless laptop or a smartphone. All it's got to do is want the same IP address to be a problem. The simplest test is to disconnect the printer then ping the desired IP address. If you get a response somebody else is using the same IP.

I had this very frustrating conversation with an IT professional not too long ago. I use a little utility called NetScan, that will pick up all IP addresses on the network, and their MAC addresses. So I was able to identify the MAC address, and from that the manufacturer of the device, which turned out to be a Samsung Smartphone. So with the IT professional on the line I asked "Who has the Samsung phone and would she please turn it off for a moment." To his great surprise this solved the issue. He refused to admit to the end that it was a duplicate IP.

Sad but true. We use 'advanced IP scanner' similarly. I'm glad my colleague who does IT support is true professional. He never underestimates my thoughts regarding MFPs and I fully trust him when in doubt.
