I've only worked for dealerships in Australia. The majority of my experience is on Xerox machines (Fuji Xerox in Australia), though I've done plenty of work on HP & Lexmark machines as well.
I've drunk enough of the Xerox kool-aid that you could describe me as a bit of a Xerox fan boy/photocopier geek.
I'll be honest, I'm not expecting a lot of questions (maybe beyond "What is wrong with my photocopier?"). Ask me anything ... I'll do my best.
