Denso QS20P-A User Manual page 17

• The time required to read a QR code is proportional to the volume of data
contained in the code. If you scan a QR code containing a large volume of
data with the QS20P-A, it may take time. Scanning low-quality codes may
also take time for completion of reading.
• Disabling reading of unnecessary types of codes may increase the scan-
ning speed.
NOTE
Before reading labels, clean them if stained.
Avoid using the QS20P-A in direct sunlight. The QS20P-A might fail to read
NOTE
correctly.
