I'd rather try an all clear before ordering a new controler board anyday etc

When you clear all or clear engine on a color mfp, you loose all factory adjustments for line position, laser diode units and in many cases, the ID sensors. These are t he settings that are maqde to each unit to get it to function properly and are different for each machine. Once you spend 2 to 4 hours doing manual line adjustments before the machine is to the point that forced line position will run without error, you will understand why we do not recommend it.

Ok - Update

Firstly thank everyone for your replies.

Secondly I went back today and completed:

Updated all firmware
Ran all the SP modes as above including the clear All Data ( last resort)

Nothing worked and the machine still doesn't respond to a ping command or opens its web page or will print.

Think I'm looking at a controller board failure??

For what it is worth, I'd say yes.
But you might try seeing if that machine will print from your laptop over a USB cable first. If that works you might see if that might be a suitable solution. I've gotten out of a jam or two that way, temporarily at least.

Make sure IEEE802.11x authentication for ethernet is set to inactive.

Toner Munkeh, you are a star, that worked and it's now printing and scanning fine, thank you so much.

Great fix! But who changed that SP setting in the first place!

It's not an SP, it's in Interface settings.
I'm sure the answer is, the office "hero" that can't help but fiddle with things, and then NEVER, EVER admit to screwing them up! Nearly every office has one!

WOW! Major props for pulling that one out of your hat!
Who would've EVER figured that out??!

After sorting the issue I was discussing the cause with the customer and he thinks a member of staff who left acrimoniously ( fired) on the Friday maybe did it?? Who knows but definitely one I will remember

The "member of staff" would have to have very intricate knowledge of Ricoh connectivity and how it would disable the machine in such a specific and difficult to find way. This setting is normally enabled when a particularly stupid IT representative wants to print to their machine from an ipad.

Not necessarily. It can be done in user tools and, if I remember correctly, from WIM. If machine and network administrator function are not password protected, many settings are easily accessed.
