DF30 Heat Press Error

[JonathanAnon]

I have a DF30 heat press that was working perfectly last week...

http://www.printerowners.co.uk/hardware ... -press.htm

I went to use it this week, and it's coming up with a flashing "4" on the interface.

Does anybody have a copy of the manual, or know why this error is appearing.

thanks,
J
