Electrophotographic technology-based printers are widely used as a printer or copier in the office, for example, because they can deliver high-quality prints at high speed and excel in printing productivity. One of electrophotographic methods uses an LED printhead as a light source for writing by the electrophotographic printer.
In 1979, we successfully brought into practical applications an electrophotographic printer adopting LED for its light source, in collaboration with NTT. Since then, OKI Digital Imaging has been engaged in technical development designing, manufacturing, and selling of LED printheads in pursuit of bringing world-leading printers into practical applications.
In 2006, we developed a device (epitaxial thin film LED array), which unites LED and LED Driver IC using the epitaxial thin film bonding technology, and made a product out of this new LED printhead. This helped make the head structure much simpler and realize the more compact yet more reliable printhead than ever.
OKI Digital Imaging constantly pursues creation to deliver products based on our original technology that can satisfy our customers.
