ABSTRACT:
A correction member driving system for a printer in which an error such as a mistyped character on a recording member is erased by an error correction member in a sequence comprising the steps of positioning a correction member at a position operatively aligned with the printing error, typing a type character corresponding to the error through the error correction member on the recording member to thereby erase the error, and separating the error correction member from the recording member by automatically forwarding the error correction member by a predetermined distance. The preferred embodiment further comprises the steps of automatically backspacing the error correction member to the erase position, and returning the error correction member to a storage position.
