Hi, I'm Sadique. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP
Take a paper towel and fold it into 4 turns and make it little thick. Then add little rubbing alcohol to it and then place it in the path of the printhead carriage. Then move the printhead carriage over it a few times.Please follow this link to see a video : http://www.youtube.com/watch?v=yrAqXjX10xsTell me if it makes any difference to your problem.
Let me clarify,
Has the printhead carriage jammed ?
Is it not moving?
I will give you a video manual which will help you to access your printhead and clean it manually.
