1-7 duplicator problem

Purchased a new 1-7 DVD duplicator with Asus Rom and Pioneer burners. All I get is error message “Source Failed T” Manual is useless. Can anybody HELP ME PLEASE. I’m a greenhorn with duplicators.

Have you asked those who sold you that?

If not then do it!

Yes asked the seller BUT no help at all. Contacted An Chen Computer and Copystar all hopeless so far!
Still needing help with "The Best Duplicator"

Are you trying to duplicate a commercial copy-protected DVD?
