ABSTRACT:
The scanner and scanning method of the present invention effect bar code scanning to determine the bar code data printed thereon by repeatedly sweeping a scanning beam in scan paths across the labels. The bar code labels bear bar codes of the type which include a primary code portion and which may also include an Add-On code portion. The method of the present invention includes the steps of sweeping a scanning beam across the label until the beam sweeps the entire primary code portion in a first scanning pass along a first scan path; immediately sweeping the scanning beam across the label in additional scanning passes along additional scan paths adjacent and parallel to the first scan path; and, if the beam sweeps the entire primary code portion in the additional scanning passes, and, if an Add-On code portion is not scanned in part during either the first or additional scanning passes, then the data scanned during the first and additional scanning passes is accepted as valid scan data. This method is carried out by a computer controlled scanner.
