Scanning PDF417 Bar Codes
The PDF417 bar code symbol has multiple rows, but the raster
pattern also has multiple scanning rows. Two basic steps are
required as you scan:
1. Point the scanner at the bar code and press the scan button.
2. As the raster pattern spreads, keep the pattern in the same hor-
izontal plane as the bar code.
3. The terminal indicates a successful scan by changing the LED
from yellow to green, beeping one or more times, and/or dis-
playing the decoded bar code on the screen.
“Tall” PDF Bar Codes
If the PDF417 symbol is “tall,” the vertical scan pattern may not be
high enough to cover it.
In this case, try a slow “up and down” scanning motion. With the
raster pattern open, try to move the scanner slowly down toward
the bottom of the symbol, keeping the beam horizontal to the rows,
and then slowly back upward toward the top.
