Common Causes of Poor Performance
The most common reasons for poor scanning performance are listed below.
♦ Bar codes are not positioned at the focal distance of the scanner.
♦ Specular reflection is impacting the scanner. Change the angle/position of the scanner or the bar code.
♦ Poor quality of printed bar codes. Bar codes are out of specification.
♦ The paper on which the bar code is printed is highly reflective or has a glossy finish causing light to be
reflected into the scanner.
♦ The distance from the scanner to the bar code is not suitable for the density of the bar code. Or the
density of the bar code beyond the scanners capability.
♦ If the red illuminating light of the scanner is not on, the scanner may be in the Trigger Enable mode
expecting a trigger signal.
Modified and/or Customized Scanners
Opticon will work with you to modify or customize scanners to match your requirements. Scanners can be
modified in terms of connectors type, pin-outs, cable length, default settings, custom software and many
other areas.
Opticon will modify scanners in our factory and ship you scanners that match your specific requirements. By
incorporating your modifications directly into production scanners, you receive scanners tailored for your
need. They can be used immediately without the need for further modification or rework.
