I can't give you much information, but I will tell you what I do know. it's a "badged" machine. It was sold under various names, ie "private labeled". It was probably made in Japan. It's a good machine, and will probably last forever. You used to be able to look at the various manual sites until you found one that matched the your machine's appearance. I was recently informed that those sites don't exist anymore. I'm not sure how to find a manual now.
If there is something specific about how to operate the machine, maybe I can help.
