USER'S GUIDE
Always check that you start scanning clearly ahead of the bar code and end
well after it; most bar code types require a “quiet zone” in front of and behind the
actual bar code. Partial scans will not render partial results!
All bar code generating software packages provide an option where a large
“quiet zone” is added to the actual bar codes. Enable this option, or use the
IRISPen’s “drop out” colors red and yellow as environment, as background color
for the bar codes - these colors won’t be picked up by the pen scanner anyway!
(This also implies that all information printed in red and yellow is not legible.)
It is interesting to note that some symbologies, UPC-A and EAN-13, are de-
signed in such a way that it makes no difference whether you scan them from left
to right or right to left!
