Recommended resolution: 200~600 dpi for regular
barcode, 300~600 dpi for QR code
Skewed barcodes may not be recognized correctly.
Using the same sheet repeatedly may decrease the
recognition accuracy due to accumulated dirt on the sheets.
If the sheet is not recognized correctly or gets smudged,
replace it with a new sheet.

Check [Enable] to detect patch codes and notify the software

A patch code is a pattern of parallel, alternating black bars and
spaces (i.e. a barcode) that is printed on a document. Patch
