The Model D4000 Provides the Two Most Popular Types of Verification: ANSI Method and-or Point-and-Shoot Traditional Method. This unique portable barcode verifier can interface with either the patented RJS Auto-Optic scan head or a laser scanner to provide nine different optic configurations. The scanners are easily installed by the user making the unit quickly adaptable to practically any verification requirement. A D4000 incorporating an Auto-Optic scanner is the industry's most flexible ANSI method verifier. Eight optical arrangements are possible via menu selections for four aperture sizes and two wavelengths of light. The optical geometry meets all requirements of the ANSI X3.182 Barcode Quality Guideline. The Auto-Optic scanner is designed and manufactured by RJS for the sole purpose of performing ANSI method barcode quality analysis. Repeatability between units is outstanding making the D4000 an ideal choice as a standardized company-wide ANSI method verifier. A D4000 incorporating a laser scanner is an extremely easy to use point-and-shoot verifier. It requires virtually no user training and analyzes most of the essential traditional verification parameters. It also provides the ANSI method Decodability calculation and percent of decode information. Popular applications include verification on materials requiring special considerations such as shiny curved or uneven surfaces and wet ink.
