Scanning 2-D Bar Codes
1. Verify that all connections are secure.
2. Aim the scanner. Try to keep the nose of the scanner parallel with
the symbol’s rows.
3. Scan a label.
•
Make sure the symbol you want to scan is within the scanning
range (3 to 8 inches). See page 1–10.
•
Press the trigger.
The scan pattern first covers the symbol horizontally.

•
Make sure the scan pattern extends at least three quarters of
an inch beyond the edges of the bar code.
If the pattern is parallel to the symbol’s rows, the pattern
spreads vertically to cover the symbol. If the pattern does not
cover the top and bottom of the symbol, pull the scanner back
until it does.
