82240B printhead fried itself in a puff of smoke

[TomC]

I have not yet examined a 82240 in detail, but this could be an 'insulation displacement' type of connector - IE the wire is not at all stripped - simply forced into the connector and the force combined with the sharp edge of the connector slices the insulation and contacts the conductor underneath. This is the 'technology' that many ribbon cables employ.

Very unusual connection technique on those wired - each wires with slight cuts in the plastic sheath and inserted physically into a slot. Not soldered at all - not sure how to reproduce the cuts in the plastic sheath of the wire. Probably will simply strip the wire bare and insert it in!
