82240B printhead fried itself in a puff of smoke

[BobVA]

Nice! Do post and let us know how it works over a few days.

Just guessing, but perhaps a mechanical failure that kept the print head from moving horizontally was the underlying fault? If it was stuck on one spot I'm pretty sure it would burn the paper, and if the motor was jammed that might drag the supply voltage down enough to cause the logic / drive circuits to go haywire shortly there after?

Thanks for validating this is the correct part!
