Info for anyone with an Epson SX515W printer, if all of a sudden your start missing print on your page, even after changing and cleaning the printer cartridge and then using the epson nozzle cleaning prog. There is another option! At the back of the printer there is a small flap which when removed gives access to two rubber tubes going from the cartridges to reservoir and then to ink jet nozzles. What I found worked a treat was to remove the rubber hoses and stick a syringe full of ethanol into both ends. It has cleared all the printing issues within 2 days. Epson printers are cheap and the in can be obtained cheap but the printing mechanism is sheet. Anyway maybe of use to someone.
