Default Re: HP Deskjet 690C. Transistor info needed.

From my days servicing HP laser printers , i very much doubt there will be any schematics available down to component level.. not outside HP or official service centres
Even with proper service manuals from HP it was usually a case of work to find area and then board swap or part swap
I think the previous reply would be the way i would go
