Canon MF5630 printer/ Belkin All in One Print Server

Hi

I run my Canon multifunction printer through the Belkin wireless print
server. When I upgraded to Vista (Ultimate) it all worked fine for a few
days, then the printer started to error. If I delete the printer and
unistall/ reinstall the print server it works fine for a while then errors
again

I'm not technical enough to know if its the server or the printer that's the
problem. From what I can see on this site, updated Canon drivers are not yet
available and I can't find anything at all on the Belkin site about the print
server as I think it's quite a new one (it is in the UK anyway). Model No
f1UP0002uk.

Has anyone had the same problem and do they know which bit of kit is causing
it and is there a solution?

Thanks

Pauline
