Is the misting / colors going left/right, or are they off vertically?
If left / right... its the head inclination. Don't try to change it yourself... its a knob that tilts/raises the head a little bit and aligns them, its held in by a screw and spring... and when you turn it, it uses little nubs to level the head (My understanding) Which causes a lot of tension on the little plastic piece... I tried to do mine and somehow the little piece of plastic that has so much tension on it broke... Now I'm out $800 (Have to replace the whole carriage) and a day worth of labor because half the printer has to be taken apart. Ontop of taking 2 weeks to get the carriage in... its a pain. Learned my lesson and never doing something I'm not too familiar with again, repair manual or not!
Go make a profile for unidirection and see if it does the same thing. I've been printing uni for the past week and its been fine, my prints looks like yours when I'm printing on a regular profile though... Hopefully friday it gets fixed finally.
