Why pay double for a T003011 brand name ink cartridge? Save 75% Compared to MSRP on the Epson T003011. Our new generations of Epson compatible inkjet cartridges contain a patented valve design. Instead of a sponge inside the cartridge to hold the ink, a valve system was designed to feed ink to the Epson printhead. Original Epson OEM ink cartridges leave 10-30% of the ink inside a cartridge when the printer tells you to replace your cartridge. By getting rid of the foam all of the ink in our ink cartridges gets used, giving you the best value and comparable results. You also have the added convenience of now being able to shake the cartridge and hear if any ink is still inside by shaking the cartridge. Because of the changes weve made our compatibles do not look identical to the OEM Epson cartridges, but they work and print the same! For use in the following printers: Stylus Color 900, Stylus Color 980, Stylus Color 900n, Stylus Color 900g. We are the exclusive reseller of LD Products brand of high quality printing supplies on Amazon.
