OKI Electric Industry Co., Ltd. (沖電気工業株式会社), commonly known as OKI or OKI Electric, is a Japanese electronics and telecommunications manufacturer headquartered in Tokyo, Japan. Founded in January 1881 by Kibataro Oki, the company manufactured Japan's first telephone and became an important contributor to the country's telecommunications industry.
Over more than 140 years, OKI has expanded into information technology, business computing, electronic equipment, banking systems, and printing solutions. Its product history includes telephone exchanges, teletypewriters, computers, automated teller machines (ATMs), fax machines, and computer printers.
Through its former printing subsidiary, Oki Data Corporation, OKI developed and marketed a wide range of printing equipment, including dot-matrix, laser, and colour LED printers. The company became particularly recognized for its LED printing technology and business-oriented C-Series and B-Series printer families.
OKI also developed networking and communications equipment for telecommunications operators, financial institutions, government agencies, and commercial customers. In 2008, its semiconductor business was transferred to ROHM Co., Ltd., as part of a corporate restructuring.
Today, OKI remains an established name in Japanese industrial electronics, telecommunications, and printing technology. Its legacy printers and other hardware continue to be used in business and industrial environments, making compatible drivers and software important for maintaining older equipment.
