I have the Buyers Lab infor and the User Manual, but have been unable to locate any service or parts info, if it exists at all. I know this is a disposable machine, but it would be great if I could find a source. Help?

Dell makes very few of their own printers. Most likely this is a re-badged Lexmark or Xerox.

I would start flipping through Buyers Lab. It is manufactured by Fuji/Xerox. There is most likely a Xerox printer that looks exactly like this one. =^..^=
