Thanks for posting your question in the Microsoft Q&A forum.
The issue you're experiencing with occasional missing digits in OCR results, particularly the last digit of numbers, can occur due to several factors:
- Even if the image appears readable to the human eye, the OCR engine may struggle with lower resolution or slightly blurred images. Ensure your scans are high-quality and have sufficient resolution (at least 300 DPI).
- If characters are too close together or touching, the engine might incorrectly segment them, leading to missed digits.
- Certain fonts or typefaces can be challenging for OCR engines, especially if they have unusual shapes for digits or if the characters are very thin.
- Small specks, lines, or other artifacts near the digits can confuse the OCR engine, causing it to misinterpret or skip characters.
- Poor contrast between the text and background can make it difficult for the OCR engine to distinguish characters accurately
