  • Data processing form for use with a scanning apparatus
    Patent number: 6695216
    Abstract: This invention is directed to a unique type of form to be used with an optical mark sensing device known as a mark read scanner for reading marks on the form. Form characteristics are defined by “graphic switches” printed near the lead edge of the form. Each “graphic switch” has four distinct settings. The expense of completely replacing the internal program of a scanner when a user requests a variation of a test form that had not been pre-programmed into the original specification of the scanner is eliminated.
