The manuals came with the machine. One is completely in Japanese. The other lists these companies:
Developed Manufactured by:
Ohiragiken Industries Co., LTD
Distributed By:
Ado Electronic Industries Co., LTD
I googled them. Ohira came back with mostly patent info. And Ado must've changed its company name at some point to: CSK ELECTRONICS CORPORATION.
I was just trying to be proactive about the supplies. I just put it in on Friday and people are using it, so I guess I will just keep looking around. Any leads would be appreciated!
