Can anyone identify what's going on here? I'm running Piezography inks on my new 9890 (about 3 weeks old!), and when I went to run my daily nozzle check I got a blank spot on MK. I've now run several types of cleanings (including ones in service mode...except for the SS Cleaning), I have swapped MK to PK (which is full of Piezo Flush), I have done the head flossing cleaning (as shown in the Inkjet Mall YouTube video), I have printed solid black, and while it has improved (from total white, to what you see in the photos), I still can't get a nice print-head test pattern.
I was wondering if someone could visually identify if this is a typical partial clog or possibly something wrong mechanically with the head.

Epson has said that, while the printer is under warranty, they will "need" to flush the Piezography inks and replace them with Epson inks before doing any service or diagnostics.
