Epson Ink Cartridges

Epson ink cartridges use a unique technology to deliver ink to the printed page. If it seems your Epson printer takes a little longer to be ready to print, you are an observant person. The Epson ink cartridge heats the ink in the cartridge. They use an old technology to make the ink flow. This technology is called the piezoelectric effect. This is the same effect you encountered in your high school labs if you ever tried to build a crystal radio, The scratching of a piece of metal across the crystal used the piezoelectric effect. It works well and the Epson printer produces some great pictures.
