    Enable the ODV-2D IMPORTANT If you make any changes to the default configuration menu items, you will be prompted to save the configuration when you attempt to put the printer online. See the Administrator’s Manual for more information. Software can automatically detect an installed ODV-1 or ODV-2D validator when the printer is powered up. This section focuses on the specifics of the ODV-2D but follows the same behavior as the ODV-1 except with ODV-2D icons and menus.

  • Page 14: Configuring The Odv-2D

    Configuring the ODV-2D Configuring the validator is done by selecting the ODV-2D icon within the Settings section. The ODV-2D comes equipped with a default setting for each configuration option, and it works without having to change any of these options. However, in some cases it is necessary to adjust these options, which are described below.

  • Page 19 Validator Action ODV-2D > Control > Validator Action The printer response is the same whether the error stems from a bad or missing bar code. It is determined by the Validator Action setting. See Vali- dator Action (Error Action) for more details on each one of these options. If the validator detects a bar code failure, the print job Stop stops.
  • Page 20 Quiet Zones ODV-2D > Control > Quiet Zones Quiet zones are the white spaces surrounding the bar code. Each bar code requires a minimum quiet zone distance in order for the bar code to be scanned properly. The validator requires a minimum distance of 1/2” or 20 times the minimum element width (x-dimension), whichever is greater, between bar codes.
  • Page 21 Num Retry ODV-2D > Control > Num Retry This option allows you to set the number of times a form will be printed be- fore the printer stops. After you clear the error message, the printer will print the same form or the next form, depending on the setting for Max Retry Ac- tion (see “Max Retry Action”...

  • Page 26 Overall Grade ODV-2D > Grading > Overall Grade This menu item sets the value used by the validator for pass/fail threshold during the analysis of bar codes. Instead of a letter grade, numbers are used to allow for more resolution. Higher values create a stricter pass criterion. The numbers can be translated to letter grades per below: Letter Grade A = 3.5 to 4.0 range Letter Grade B = 2.5 to 3.4 range...
  • Page 27 A side effect of the ANSI specified algorithm is that the Overall Grade may be lower than any of the averaged analysis parameters. This occurs because the Overall Grade is based on the lowest grade on any scan converted to a single digit grade (A to F, 4 to 0) which is then averaged. This usually occurs when a single analysis parameter has a value just above or just below the Overall Grade.

  • Page 28: Modulation

    Percent Decode ODV-2D > Grading > Percent Decode You can set how strict the validator grades each bar code. For example, setting Percent Decode to 60% means that 60% of the scanned bar code must be readable for the ODV-2D to give the bar code a passing grade. The higher the percentage value chosen, the stricter the validator grades.

  • Page 29: Symbol Contrast

    EC Min ODV-2D > Grading > EC Min This menu item sets the minimum edge contrast, which is the worst edge transition (bar to space or space to bar) used by the ODV-2D for pass/fail threshold during the analysis of bar codes. Bar codes with an edge contrast below this threshold will fail.

  • Page 30: Fixed Pattern Damage

    Fixed Pattern Damage ODV-2D > Grading > Fixed Pat. Damage Fixed Pattern Damage is a measurement of damage to the finder pattern where modulation scores for the fixed pattern portions of 2D matrix barcodes are degraded. This failure may be caused by physical damage to the code such as a mark or scuff or may be due to printing errors such as a bad print head.

  • Page 31: Unused Error Correction Code

    Unused Error Correction ODV-2D > Grading > Unused Error Corr. Unused Error Correction is a measurement of the amount of margin availa- ble to recover damage using error correction. Low unused error correction is usually due to regional or spot damage in the code. The ODV-2D will fail any barcode with an unused error correction at or below the value set in this menu, regardless of overall grade.

  • Page 38: Print Speed Limits

    There are several factors which contribute to successful bar code validation, including printer speed, on-demand print settings, calibration, and ambient light. The following sections describe how to ensure your ODV-2D validator is scanning and reporting properly. Print Speed Limits The print speed limits of 2-8 IPS are based on steady paper motion and the ability of the ODV-2D camera system to gather and process the data effectively in real-time.

This may involve rotating the form or moving the bar code to a different position on the form. PTX_SETUP Control There are several PTX_SETUP commands that configure the ODV-2D symbologies and orientations that will be processed or ignored, including the ability to skip processing entire labels.

When enabled, UPC and EAN bar- ON or 1 UPC/EAN codes will be processed. Otherwise, OFF or 0 they will be ignored on the label.

  • Page 41: Bar Code Failures

    Bar Code Failures The ODV-2D tells the printer to announce a fault condition in two situations: • When the validator detects a bad bar code • When the validator detects no bar code where it expects to find one. How the printer reacts to these faults is determined by the printer’s configuration settings, as described in this section.

  • Page 42: Bad Bar Code Error Detection

    Bad Bar Code Error Detection The ODV-2D examines every bar code that passes under the beam and sends an analysis report to the printer. If a bar code is reported to have failed to meet any of the acceptance criteria, an error condition is reported.
  • Page 43 reprinted. Scanned. If error persists, it will be tagged as failed, even Rescan&Stop though it was never scanned. Stop If the ODV-2D detects a bar code failure, the print job stops, the printer status indicator lamp flashes, the alarm sounds, and the appropriate error message displays. The printer remains in a fault condition until you press the PAUSE key.

  • Page 46: Troubleshooting

    Troubleshooting Error Messages The ODV-2D can detect several errors. When one of these errors occurs, the validator alerts the printer to perform the currently selected error action (see “Validator Action (Error Action)”) and show the appropriate error message on the printer display. Validator error messages are explained in Table 6. Table 6.
