but the reader fails to decode the
symbol.

does not transmit the symbol data to
the host.
The host displays decoded data
incorrectly.
Note: If the reader still experiences problems after performing these checks, visit your regional Omron
website to contact customer support.

8 Troubleshooting
Possible Solutions
Power to the V460-H is provided by a
PoE injector (IEEE 802.3af). Ensure
that the PoE injector is turned on and
the cables are connected properly.
Re-connect cables.
Enable the aiming pattern.
Configure the reader for the correct
code type.
Scan test symbols of the same code
type to determine if the barcode is
damaged.
Move the symbol completely within the
aiming pattern.
Move the symbol completely within the
field of view (aiming pattern does NOT
define the FOV). For long barcodes,
move the symbol so that it is in the
center of the aiming pattern.
Move the reader closer to or further
from the barcode. For barcodes and
many flat DPM parts, start at
approximately 4" (+/- 100 mm) to 6"
(+/- 150 mm) and with some tilt (+/- 15
degrees). For shiny, cylindrical, or
curved parts, force the close-up mode
by moving the part very close – from
contact to approximately 0.25" (+/- 6 mm).
Use WebLink to set the appropriate
HH
host type.
Re-connect the cable.
Program the correct data output
conditions (e.g., UPC-E to UPC-A
Conversion).
