• Aren’t smeared, rough, scratched, or exhibiting voids.
• Aren’t coated with frost or water droplets on the surface.
• Are enabled in the base or Access Point to which the scanner connects.
Is the barcode displayed but not entered into the application?
The barcode is displayed on the host device correctly, but you still have to press a 
key to enter it (the Enter/Return key or the Tab key, for example).
• You need to program a suffix. Programming a suffix enables the scanner to 
output the barcode data plus the key you need (such as “CR”) to enter the data 
into your application. Refer to Prefix/Suffix Overview on page 125 for further 
information.
The scanner won’t read your barcode at all.
• Scan the sample barcodes in the back of this manual. If the scanner reads the 
sample barcodes, check that your barcode is readable.
• Verify that your barcode symbology is enabled (see Chapter 8).
