White lines in the printout

If the lines are horizontal (across the page) it is quite possible that your refilled carts are at fault. I would suggest you try the underhead cleaning method as described in my previous post - http://www.fixya.com/support/t138226-printer_not_printing If this has little effect I would suggest you bin the refilled carts and get a full set of genuine ones to put in. The refill process can easily introduce air into the sponge which retains it and causes the ink to foam. This is then dragged down into the print head and and causes problems with print quality. If you still have issues after the underhead cleaning and new carts have been installed, get in touch with The Service Manual Shop and get the Epson software they have which allows you to make lots of adjustments to the printer. You should try running the alignment routines to check the Bi-Di printing is inline.
