Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
Currently, what type of paper are you using?
Also, do you have the printer connected by usb, or wirelessly?
One more thing, as a test can you place a document on the scanner glass then hit color copy, ( do not use the computer, j ust the Epson printer )
Does it put too much ink on the copied document?
