Throw ink

I have serious problems when printing, I have already changed the print heads, I have sharpness in the image, good color, but the printer has started to throw ink in the middle of printing and I do not know how to solve it, can someone help me, please

Hi @gcgartwork8370, I recommend first cleaning the pinch wheels. If the issue persists, increase the curing. If this is not fixing the issue, decrease the vacuum. I hope it helps.
