RJS SV Series Scanner/Verifier
Statement of Compliance

The RJS Series of Scanner/Verifiers gathers data per the ANSI/ISO method of verification to perform practically all the industry standard bar code quality parameter calculations. These include all ANSI/ISO method parameters, PCS, ratio, X dimension calculation, modulo check digit calculations, average bar deviation, etc.

Reflectance Compliance – 660 nm wavelength (red) light
The reflectance values embedded in the calibration symbol supplied with each SV unit are traceable to Applied Image Primary Verification Calibrated Standard per ANSI X3.182 Step Reflectance Chart (see note 2.) Applied Image certified Calibration Standards are manufactured to Applied Image, Inc. and Uniform Code Council, Inc. specifications, using ANSI X3.182-1990 methodology, and are calibrated using standards traceable to the National Institute of Standards and Technology (N.I.S.T.) 

ANSI/ISO Method Compliance
The RJS SV Series gathers data and performs all ANSI/ISO method parameter calculations per the ISO/IEC 15416 and ANSI X3.182-1990 methodologies with a few exceptions. The exceptions are related to the instrument’s design and mission. The design incorporates a proprietary analog laser scanner that can be assembled with various focus lengths to produce different beam sizes. The mission is to not only analyze bar code quality, but also to detect any printer failures, process failures or media problems.  For maximum performance, a fixed mounting distance and angle are required. A beam spot size able to detect errors of the particular print method is highly recommended.  This beam spot size may or may not correspond to the recommendations in various specifications that it be related to the X dimension of a particular symbol, but instead correspond to the printer’s resolution or some other parameter(s) critical in the application. A major philosophy of an on-line verification system is; if the printer and/or process is operating correctly and the media has proper reflectance properties, the best print quality for that particular print method and material is achieved by definition.

Notes

1.        The SV Series can be calibrated to practically any reflectance standard. Internal high and low calibration reflectance normalization settings are user programmable via commands.

2.        Final system tests are performed at the proper focus distance and at an angle of 22 degrees. Units with common focus distances are checked to yield analysis results within +/- 4 % of all target values.

3.        SV models with an 8 inch focus distance have a spot size that gathers light very similar to a 6 mil round aperture. For these models, final test includes analyzing UPC symbols on the Calibrated Conformance Standard Test Card for EAN/UPC Symbol Verifiers. Results are checked to be within +/- 4% of the marked values on the test card. SV100 and SV200-1 are examples of models with a focus distance of 8 inches.
 

Exceptions to the ANSI/ISO method

1.        The Defects calculation does not include the quiet zone area. A separate quiet zone check is implemented to easier isolate print problems vs. setup problems in an on-line environment.

2.        A laser spot is used instead of a round aperture. The spot size is dependent on the focus distance of the unit’s optical system.
