Barcode Sample
UPC specified in “Barcode Test Labels” on page 17. (Resolution: 0.33 mm,
PCS: 0.3)
MRD = Minimum reflectance of white space - Maximum reflectance of black bar
PCS =
Reflectance of white space - Reflectance of black bar
Reflectance of white space
Note: Make sure that the optical window is clean and free from scratches. A dirty or damaged
optical window may decrease reading performance.
