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.
