Since the print head got banged around it would be a good idea to do a print head alignment using the Epson Printer Utility. Also you could leave the printer on 24/7. Turning it off every day and then on again uses a lot of ink at start up. Just print a small color file at least every other day...
I have always used Epson printers except for the first ever inkjet printer made by Hewlett Packard. As long as Epson continues to rip off the user with outrageous prices on ink cart replacement I will do everything I can to replace the ink with 3rd party products. I despise greed.
