Most office equipment never comes with schematics. My best advice is to contact HP customer support, and tell them what's going on. Short of that, you might try taking it to a shop that fixes printers and see if they'll let you look at their schematics... Although my guess is that they fix by replacing entire modules and not individual electronic parts.

Good luck
