Possible Solutions
Program the scanner to read that type
of bar code. See Chapter 8,
Symbologies.

code type to determine if the bar code
is defaced.
Move the scanner closer to or further
from the bar code. See Decode Zones
on page 2-6.
Move the symbol until the scan line is
within the acceptable aiming pattern.
See Figure 2-3 on page 2-4.
Scan the appropriate host type
programming bar code. See the
chapter corresponding to the host
type.
Check for loose cable connection and
re-connect cable.
Ensure the scanner's conversion
