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 paper background is not white, but some color like dark blue, causing poor contrast.

♦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 is 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.

♦If the com port setting is set to Handshaking, the scanner will not transmit until the CTS signal (RTS from Host) is activated.

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 connector 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.
