Heidel prosetter voltage issue

[Touchsigna]

I keep getting a 3301 voltage failure, 3014 mirror unit error, and 3201 optichead error when starting up a Heidelberg Prosetter. I've cleared the airlines as best as I can, and got a plate out, but now I get the voltage error. Anybody have any similar issues and suggestions?

Dear Touchsigna,

Error 3301 is positive 42 volt failed. I guess you have power supply or P-Backplane faulty. Please check.
