Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I advise you to cease use of 'magic bullet' at once.
Run normal cleaning cycles several times (with pauses of 1/3 hour or more between cleaning cycles.) These 'head cleanings' can be done from the software provided with your Epson machine, and need involve 'magic bullet' or other devices not at all.
That may help clear up the problem. (If you were injecting cleaning fluid into or onto the printheads, that may take some purging of ink through it - which is what the 'head cleaning' cycles in your Epson printer's Maintenance functions, should do.)
Let me know how it turns out, please.
