Barcode Reading Failures: Quiet Zone and ITF Digit Skipping Troubleshooting Guide

This document addresses common barcode reading failures, focusing on the "quiet zone" issue where insufficient white space around a barcode prevents scanning, and the "digit skipping" problem specific to ITF barcodes due to pattern ambiguity. It provides diagnostic tests and solutions, such as adding white paper to verify quiet zone requirements and using the Digit Specification function to prevent data loss.
