The printhead operates at frequencies up to about 50 kHz and is compatible with pigment inks. It has historically served as a replacement for earlier F1910x/ F1910x variants (e.g., F191110, F191040, F191080, etc.) and is frequently sold as the genuine Epson part for the Stylus Pro 7000/7700/7900/9700/9900 series and associated SureColor configurations. The Epson F191140 Printhead is marketed as the direct successor to those older F191xxx models, consolidating compatibility across multiple printer families.
