I just started switching from epson to cone inks. I installed light magenta, and it worked for a day or so, and then clogged. i did a power cleaning, ran out of two others. None of the cone inks are working, all clogged. they are primed (ink coming out of the whole), but they are clogged and no ink comes out in a test print. Spoke to Wells, and opened air vents. Made 4 small prints. Still not working. Please help. In a rush to get this working.
