My Pro 100 needs a new print head. Any suggestions on where to get one?
Can you define a dead nozzle for me please? I ask because I assume the channel has flow when flushing but not when printing? I'm asking because I have one single color channel in a Pro-100 printhead that refuses any flow whatsoever. I can't imagine what could be blocking the flow inside the unit.I got one that was not sealed but had been put back in its plastic carrier. Reported being installed years prior, and hit the error about being installed in a different model before. Put my Pro-2000 in service mode and bypassed that software lockout only to find dead nozzles. I wasted a few hundred at least in ink and MT costs before finally concluding it was for-sure dead and getting a refund for the head itself. Got a different one for a bit more, from some Japanese seller. Came way faster than expected, and it's been going in my printer ever since.
A dead nozzle, at least in my experience, is when a thermal print head nozzle has been electrically destroyed (usually by overheating, or running it dry which is just extreme overheating speedrun). I suppose yeah it would probably still pass ink during a cleaning cycle since the purge plate is mechanically flowing ink, not electrically firing it. But ink or not, it won't ever fire ink during printing. If I understand correctly -- Canon print heads are resistively fired (think of it as a thin wire that gets hot when you put electricity through it) so if you overload it without cooling, the line just blows open physically from my understanding. Here's a literal resistor overloading and blowing open to get the idea across -- a resistive nozzle element would just be a microscopic version of this in essence.Can you define a dead nozzle for me please?

This is exactly what I am silver lining this project as. I'm going to do some more testing with it. But every other color works and I only print in grayscale 95% of the time. If my attempts at restoring flow to the channel don't work, I'll adopt it for grayscale prints.Usually, when a whole channel comes blank in the nozzle test and all the others are fine it means that an electronic component controlling the output of this channel has failed. Depending on the design of the printhead, sometimes only 25% or 50% of the nozzles are disabled, but the outcome it's the same : a new printhead is needed, unless you're OK. printing without that color in particular (for instance, if you print only black text ).
