When the scanner is able to read the barcode the problem may be caused by the incorrect host interpretation of the USB protocol. Please use the following setting codes to adjust the USB speeds.
．USB0: Regular speed mode. Usually for older operating systems like Windows 98 when default setting is not working.
．USB1: Full speed mode. The default speed of the scanner.
．USB2: Middle speed mode. Usually for Mac O.S. or Linux O.S when default setting is not working.
Please follow the steps below and refer to the Programming Guide to set the minimum or maximum length.
Normally the quiet zone has to be observed as necessary when making the barcodes.
