the machine is cleaned regularly. this started after I switched from Eco-sol maxx inks to Maxx life eco sol inks by Genesis. It is worse by far with the black/blue. I can print a run of 4' or so of solid process color and all goes back to right...but only while a print session is in process. Very next day, same thing happens again. Obviously it's WASTEFUL, and expensive. Any pointers? I am switching back to OEM inks as soon as this runs out just to see if that might be the thing...but beyond that...?
