Assuming you've run cleaning cycles and it's printing pink!
I read an article some time ago and it suggested that the quickest and least complicated way to to get your prints the same as the colours displayed on your monitor is to print off a test print, then when it's dry adjust the colours on your monitor to those on your print. I haven't tried it myself as I use Adobe Gamma Monitor, a small program which comes with PhotoShop.
I did a search on the internet regarding cleaning Epson Printers. One site had suggested putting Heat Sink Tubing (like see through straws) over each of the ink nozzles and putting a clear window cleaning solution in the tube (cut to about one and a half inches) and leaving the solution to drip through the nozzles. There are a number of things you can find on a google search.
