The Falcon does not accept
scan input.
The scanning window is dirty. Carefully wipe the scanning window with a soft, clean
cloth. Do not use abrasive cleaners.
The scanning application is not
loaded.
Verify that the unit is loaded with a scanning applica-
tion. See your System Administrator.
Unreadable bar code. Be sure the symbol is not defaced.
Distance between exit window
and bar code is incorrect.
Be sure you are within proper scanning range.
The Falcon is not programmed
for that symbology.
Be sure the terminal is programmed to accept the type
of bar code you are scanning. Try using FF3A to turn
on maximum defaults, as described in “Programming
Parameters” in the Falcon 4400 PRG.
The Falcon is not programmed
to generate a beep.
If you are expecting a beep on a good decode and
don’t hear one, check that the application is set to gen-
erate a beep on good decode.
Battery is low. If the scanner stops emitting a laser beam when you
press the trigger, check your battery level. Refer to the
PRG.
Note: If the scanner is still not reading sym-
bols, contact your distributor or Datalogic.
The UPC/EAN extension
(supplemental label) is not
always scanned.
Laser beam only crosses over
base of UPC/EAN label.
Set the Read Verification for extensions (parameter
0528) to a value lower than the
Read Verification for
the base label. See the PRG.
