I did not use the printer Epson Pro 4900 for a long time and even after 5 or 6 powerful manual cleanings for all inks the paper was staying completely white !! I did the Ink Charge and cleaning process described in the soft and after that the machine is working 100% fine In France there is no way to get this software except if you work for Epson !!!

Very helpful - thank you. I was stuck as I use a Mac and your Mac software saved the day. I used the trial key this time to be sure it worked, but will be happy to purchase one when I need it next.
