Epson 600 printer

Hello, can anyone help me with ? on why my epson 600 won't print.
I took apart the printer and cleaned the printhead out, I know there is not a clogged printhead, because I can see the water coming out of printhead when I shot water from it.
Put in new ink cart. It is going through the motions like it is printing text, but the text is not showing up on paper. Please help!!!
Thanks Heather
