6 Operation
The scanner can read barcodes in either sweep or presentation mode to
accommodate different requirements. Sweep mode means moving items
through the scan volume. Left to right, right to left, top to bottom, bottom to top,
etc. are all okay. This scanner is truly omni directional. Sweep scanning is usu-
ally used for high throughput and reduced product handling. Presentation scan-
ning is used where counter top space is at a premium. The product is moved
toward the scan window (“presented”) until the barcode is read, then the prod-
uct is removed.
