Adam Printer Help

[Milli V]

Hi - am refurbishing an Adam for resale and have an issue with the printer. The print head does not strike the daisy wheel when I print - The relay is not making the plunger move. I swapped heads and it is the same on the other head, anyone know where on the circuit board this may be controlled? I am thinking that maybe a capicitor or something is bad

 

Any help is appreciated
