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 would advise you to consider whether it might ultimately be caused by a leaking (cyan) ink cartridge. They often do leak, after all. And if the cartridges you bought were at all a 'budget' item, or cheap to put it bluntly, then that is all the more likely.
