decode the bar code.
Scanner is not programmed for the cor-
rect bar code type. Program the scanner to read that type of bar
code. See

Distance between scanner and bar code
is incorrect.
Move the scanner closer to or further from
the bar code. See

Move the bar code until the scan line is
within the acceptable aiming pattern. See
Figure 5 .
