Epson Stylus Office T40W
Intelligent Ink Cartridge System
Each of the Stylus Office T40W’s separate ink cartridges contain sophisticated circuitry, which tracks and maintains an accurate record of how much ink has been used and the amount of ink remaining. So, even if you remove a cartridge then reinstall it, the Stylus Office T40W’s printer driver knows immediately how much ink is still in the cartridge.
Now, instead of running out of ink halfway through a print, the printer driver automatically checks on the amount of ink in each cartridge then displays an early warning if the ink level in any of the cartridges is approaching empty. It’s the best possible system for using full cartridges for large print jobs, whilst making the most out of partly used cartridges for other smaller jobs. Maximum ink usage, maximum benefits.
