If a barcode reader is reading codes incorrectly, what is the first appropriate step?

Answer and explanation

Correct answer: Clean the barcode and reader surface, then scan again

The governing troubleshooting principle is to check simple physical causes before making software or data changes. Dust, smudges, damaged labels, or dirt on the scanner window can interfere with the reflected light pattern and produce an incorrect reading. Therefore, clean the barcode and scanning surface and try again, making option A correct. Driver removal may be considered later; replacing a monitor or deleting records does not solve the scanning cause.
