  • Method and apparatus for band printing with automatic home compensation
    Patent number: 5046413
    Abstract: A system and method for automatically compensating for inaccuracies in the positioning of the timing mark sensor of a band line printer. A selected hammer is operated to impact a test character and an adjacent space between characters or a space provided by a blank character on the type band. The flight times of the hammer for the character and space impacts are measured under control of a microprocessor programmed to locate the edge of the test character and to compute a timing adjustment value for use by the printer control to obtain centered impacts of characters during printing.
