I have a CET K2 250 that we've had in the shop for about 8 months. I'm about to put in a 3rd Kyocera print head to the tune of $8000!! I have constant clogging, banding, ink fall out and have to flush often. I use Nutec inks and recently heard that may be my problem. Anyone else have similar issues with these inks? It seems to be the cyan that causes the biggest problem.
