Question about HP DeskJet 1220c InkJet Printer
With the electronics experience you have, changing of Cap and MOSFIT's, I must ask this question... Why, do you not have real projects to get into ??
If you have powered up the unit without the drain of the motors and after connecting the 4-motors and others you still pull to much current, I would continue tracing backwards.
I would check the rating of the FET"s and if you have to replace them anyway, Go larger, I wonder if the caps also took a dive. You ordered your FET's in a pair and not just replacing one at a time ? Sorry, just had to ask.. You got too much experience for this, Your like me, can't trash anything with a major attempt.
