Inspector 4000 Statement of Compliance

Inspector Model 4000 Statement of Compliance

The RJS Inspector 4000 performs the ISO/ANSI method of verification. This document is intended to describe the verifier’s standards of compliance.

Reflectance Compliance – 660 nm wavelength (red) light   (see note 1)

The calibration plaque supplied with the Inspector 4000 is RJS part number 930-08. The plaque’s 660 nm (red) reflectance values are traceable to the Applied Image Primary Verification Calibrated Standard per ANSI X3.182 Step Reflectance Chart (see note 2).

Reflectance Compliance – 925 nm wavelength (infra-red) light   (see note 1)

The 925 nm (infra-red) calibration plaque reflectance values are traceable to RJS standards developed between 1975 and 1978 for the initial Autoscan product.

ANSI Verification Method Compliance

The RJS Inspector 4000 gathers data and performs all ISO/ANSI method parameter calculations per the ISO/IEC 15416 and ANSI X3.182-1990 methodologies with special considerations and exceptions described in a following section. The Inspector 4000 also conforms to ISO/IEC 15426 per the requirements specified in Section 2.

No optical correction algorithms are incorporated in this system. One RJS proprietary calculation correction algorithm is incorporated to provide a more accurate and consistent Decodability calculation for manual scanning. This algorithm produces maximum accuracy for Decodability when a symbol is scanned in both directions during a multiple scan analysis.

The optical configuration meets all aspects of the X3.182-1990 and ISO/IEC 15416 requirements.

The four round apertures used for the ANSI verification method are each physically inspected and measured to be within +/- .0004 inch of their intended diameter sizes when in the final optical configuration.

Final system test is performed by scanning a set of test symbols that are traceable to Applied Image U.P.C. Primary Verification Standard (per ANSI X3.182) calibrated at 660 nm and 6 mil aperture (or 5 mil depending on the scanner model being tested.) All calculated parameters are confirmed to be within +/- 4 % of all target parameters marked on the symbols (see notes 1 and 2).


  1. The Inspector 4000 can be set up to be calibrated to practically any reflectance standard. High and low calibration reflectance target values for both the red and infra-red light sources are user programmable via menus.
  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.)

Special Considerations and Exceptions

  1. Average bar deviation is displayed in a proprietary graphic format in units of % of tolerance. It meets the intent of providing a print trend for ink spread with the additional advantages of providing a high resolution format that enables meaningful warning and reject messages based on published traditional tolerance specifications.
  2. Except for when an AIAG subsymbology is enabled and a Code 39 symbol is analyzed, the unit displays all individual ISO/ANSI parameter averages in letter (A through F) format. The unit always displays the overall symbol grade in both letter and numeric format.
