Abstract
An electronic typewriter with an electronic spelling dictionary feature included therein automatically adds a code signal to a code memory register corresponding to a print position of a printed error. The printed error is detected by the dictionary feature in response to printing operations. The electronic typewriter also automatically repositions a print hammer of a printing mechanism to the printed error position from a position beyond the printed error. This is accomplished by an operator actuating a key or a multiple key sequence for finding the printed error by the electronics searching for and finding the added code signal.
