Conditions
Barcode Sample: OPTOELECTRONICS Test Sample
Distance: 120 mm from the edge of the scanner
Label: PCS = 0.9, Resolution = 0.26 mm, Quiet Zone = 10 mm
Angle: Skew Angle β = +15°
Scanning performance may fail due to the specular reflection of illumination LED when
the reflectivity is high. Either of the following solutions will help solve the problem.
• Tilt the scanner 15 degrees in the skew direction when scanning.
• Set the illumination LED OFF. When turning the illumination LED OFF, make sure
the ambient light immunity is 500 lx or more; otherwise; scanning performance
may be decreased.
8.6. Scanning Barcodes on Moving Items
The value of motion tolerance can only be met when the auto-focus adjustment has been
performed. Ambient light reflections might affect the detection of the scan field and the
time that is required for scanning.
