I have been trying to clear what I thought was a clogged channel without any luck. I’ve tried the piezoflush/bounty printhead cleaning routine several times (thanks for the very clear video) as well as replacing the wiper blade assembly.

Is there anything else I can try to unclog it, or is the printhead dead?
