Xerox Phaser 6510 printer (not working?) (Bolstone HR2)

On offer is a Xerox Phaser 6510 colour duplex network printer.
However, it does not work. It turns on and remains stuck on an error message.
It’s quite new and apparently it only printed less than a couple of thousand pages. It comes with nearly new toner (I discovered it because at one time it did go past the error message).
I was given it to have a go, and I did have a go at it.
If you feel like having a go at it yourself, you are welcome to it.
If you get it to work, it’s a great printer.
Ideas on how to get it to work (even if you don’t want it) will also be gratefully accepted (I wouldn’t mind offers for a replacement free colour laser printer either).
Please note that I am located about 4 miles south of Hereford, not far from Little Dewchuch.
