The unit powers 
up, but does not 
scan and/or 
beep. 

The bar code being 
scanned does not 
satisfy the configured 
criteria for character 
length lock or 
minimum length.  

Verify that the bar code being 
scanned falls into the configured 
criteria. 
 
The scanner defaults to a 
minimum of 3 character bar code. 

The unit scans a 
bar code, but 
locks up after the 
first scan and the 
red LED stays 
on. 

The unit is configured 
to support some form 
of host handshaking 
but is not receiving 
the signal. 

If the unit is setup to support 
ACK/NAK, RTS/CTS, XON/XOFF 
or D/E, verify that the host cable 
and host are supporting the 
handshaking properly. 

The unit scans, 
but the data 
transmitted to the 
host is incorrect. 

The unit’s data format 
does not match the 
host system’s 
requirements. 

Verify that the unit’s data format 
matches that required by the host. 
Make sure that the unit is 
connected to the proper host port. 

The print quality of 
the bar code is 
suspect. 

The aspect ratio of 
the bar code is out of 
tolerance. 

Check the print mode. The type of 
printer could be the problem.  
Change the print settings.  
 
i.e.  Change to econo mode or 

high speed. 

The bar code may 
have been printed 
incorrectly. 

The unit is not 
configured correctly 
for the type of bar 
code being scanned. 

Check if it is a check 
digit/character/or border problem. 

The unit beeps 
at some bar 
codes but NOT 
for others of the 
same bar code 
symbology. 

The minimum symbol 
length setting does 
not work with the bar 
code. 

Check if the correct minimum 
symbol length is set. 

The unit scans 
the bar code but 
there is no data. 

The unit’s 
configuration is not 
correct. 

Make sure the scanner is 
configured for the appropriate 
mode.
