This was a high-speed printer for Fujitsu's large general-purpose computers. It featured a new mechanism and design, based on the proven technology of the previous FACOM 642, and had improved printing and paper feed speed, greater ease of operation, and reduced noise during printing. This printer was completed in November 1971, and was used primarily with the FACOM 230-45S/55/60/75 and FACOM 230-8 Series of large general-purpose computers. It had the following features:
- 1) A printing speed 25% higher than the previous FACOM 642 was achieved by improving paper feed speed and increasing rotation speed of the type drum.
- 2) Fujitsu responded to user needs by developing the first dedicated "form stacker" for fully automated paper handling after printing.
- 3) Reliability and stability were improved by using a powerful 5-phase pulse motor for the paper feed mechanism.
