82240B printhead fried itself in a puff of smoke

Thanks Tom - was hoping it wouldn't come to that - peeling up those nicely aligned rubber feet.
Sure enough, 4 more screws under the feet, easily undone and voila innards exposed:



Capacitors look in good condition, though testing the them with my digital multimeter gave me wildly different readings vs. what is printed on them. I think this is because they are still connected to the circuit board. Or even more likely is that its not so simple to test capacitors, as I've read.
