I don't think that we can exclusively blame overheating as root cause of print head electrical failure. Something is failing in the print head, though...Why are Canon print heads suffering from what looks like a clog but is in fact now known clearly to be electrical failure? (Over heating)
I think this problem has not been highlighted enough and is not going to go away any time soon so users should be aware that it might happen to them.
This only seems to affect the larger print heads 8+ or more colours and could possibly affect both dye and pigment machines; so far there was not much we can do about it because we were too quick to blame the inks.
One suggestion was made in another thread way back, which (I can’t find) I think it was @turbguy, to try and reduce the strain on a print head by running your printer in (Quiet Mode), now some may phoo phoo that as nonsense but could that be the answer we’re looking for ! !
Edit:- Thanks @PeterBJ ..
That said, I believe that the issue really is rooted in the designer yielding to pressure from the marketing department to produce a faster printer, which stresses (NOT STRAINS) everything in the machine. As long as a certain percentage of machines sold lasts through the warrantee period, the OEM "wins"...
Oh, and use more ink colors too! That way, we can sell more carts! (and the designer grumbles, "heat load", "smaller circuit elements", "higher current densities"....).
There's something to be said for piezo print heads...
