6.2. Printed Contrast Signal
0.45 (MRD 32%) or higher (over 70% of reflectivity of space and )
*Scanning performance may decline if dirt or scratches mar the optical window. Keep the optical
window clean.

*When scanning symbologies printed on highly glazed paper such as glossy paper or card case, scanning
performance of this data collector may decline due to the specular reflection of LEDs. In such cases, adjust
scanning angle by incline the data collector to 15 degrees toward the skew direction to improve scanning
performance. When turning off the lighting LED, it may decline the scanning performance unless the ambient
light is 1000 lx or higher. Also, the light or reflection light caught by the camera may decline scanning
performance, when using codes on the above described paper.
