Portable Verification FAQ
Question: Does a Laser Inspector or D4000 w/laser provide a “letter grade”?
Answer: No – not in respect to the situation where the letter grade means the ANSI/ISO Overall Symbol grade.

The laser modes for RJS portable verifiers provide traditional types of analyses. They do however include one of the ANSI/ISO parameters called Decodability (“d/bility” shown on the LCD) and this is displayed as a calculation value and a letter grade. This is one of the parameters that create an overall symbol grade and is useful for checking bar and space print accuracy in conjunction with the avg. bar deviation calculation. The D4000 Auto Optic is the correct unit if you need a full ISO/ANSI bar code verifier.

Question: What model portable verifier should I use to analyze bar codes printed on a thermal or thermal transfer printer?
Answer: The recommended model is Inspector D4000 Auto Optic. This is the most economical ISO/ANSI verifier in the product line and will check all thermal printer failures. The particular failure that needs the ISO/ANSI/ method to detect is a failed print head element that causes a white stripe inside a bar of the bar code. This results in a low Overall Symbol Grade (C or less) due to a low Defects calculation.
Question: What model portable verifier shall I use to analyze large direct marked bar codes on corrugated media?
Answer: The recommended model is D4000 Auto Optic scan head. The patented scan head includes a 20 mil aperture choice to meet industry standards. Additionally, the scanner’s size and feel makes it easy to scan corrugated material.
Question: Can I send analysis data to a PC?
Answer: Yes, we suggest you look at the Verifier Computer Interface Report. This allows downloading to your computer the inspection report, Scan Reflectance Profile, and generation of an Excel spreadsheet of multiple bar codes..
