Unfortunately my order for the new MTP201G-166-E printhead just got refunded by an Australian electronics supplier. They said:

We have had to cancel and refund your order today, again our apologies for this inconvenience caused.

Hmm. Perhaps this is a sign that I should check the signals and voltages first before attempting to order this again from somewhere else! :-) I wonder if this part is restricted worldwide or just in Australia - I suspect its worldwide. Not sure how to get hold of this part now...

Did you ever get this resolved?
I just had the exact same thing happen.

I have two replacement print heads on order but I also suspect the problem was caused by some other component. The print head itself does not seem to have any intelligence to it. The printer controller chip or the CPU could be at fault. I sure don't want to burn a brand new print head...
