Notes
When a barcode is printed on glossy paper or a card case, it may cause difficulties in
scanning due to the reflection of lighting LEDs. To improve scanning performance
under these circumstances, scan the barcode with a scan angle of 15 degrees or with
lighting LEDs turned off. When scanning a barcode with lighting LEDs turned off,
confirm that there is enough ambient lighting in the room (1000 lx or higher), or
scanning performance may decline. Scanning performance may also decline if room
light reflects on the barcode surface.
