Abstract: A device has been designed to set automatically the printer light selection lever on the Models D and J Bell & Howell printers. Punched paper tape containing the printer light sequence is prepared on a Keyboard-Perforator. This paper tape is fed into a tape reader. The electrical signals produced in the reader are then decoded by a computer unit which in turn directs a servo unit in its manipulation of the printer lever. The action of the device is considerably more rapid and accurate than manual performance and it can, of course, operate in total darkness. The robot unit is easily installed on the printing machine and it demands no mechanical alteration of the printing equipment.
