P7000 clogs on LC and LK channels

I have had these clogs on the LC and LK channels of my printer, cleaned the capping station and wiper blade, per the video posted by inkjetmall.com. This did not make a big difference. My question is, using a single cartridge with Piezo fluid may help unclog these? I am including an image of my last nozzle check (not sure if I am doing this successfully). Any comments would be helpflul. Thank you.

Please post a small pic on this thread. The large one did not come through.

It could be de-laminated.


Hello walkerblackwell, I apologize for not having replied before, here is the image of the test print I made. Please let me know if you think the head may be delaminated. Thank you.

It has delaminated.

Sorry for your loss
