Et-7700 No longer printing after print head cleaning

[bountycrook]

The print head was clogged, build up of ink gunk on the print head. I disassembled the print head and wiped the face off with isopropyl alcohol and cotton pads. I also cleaned the gunk off the wiper blade and cleaned the sponges off. Now I get no ink dispensing out of the print head where as before I was getting some ink even if it looks awful.

I guess I needed to prime the ink nozzles? I used some silicone tubing and the air output of a powered infant nose sucker and pumped from the fill port of the tanks while it was printing.
