Image scanner causes Firefox Error Console to continously pop up

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use of Honeywell Genesis 7580
2.
3.

What is the expected output? Typical page 

What do you see instead? Error Console pops up

What version of the product are you using? 1.2 On what operating system? 
Windows XP

Please provide any additional information below.
I just plugged the above scanner. It's supposed to be able to read barcode 
image from cell phone. That works fine, but for some reason it causes errors in 
Firefox stating that the combine.php which uses selfcheck.css and thickbox.css 
has errors in multiple lines. 

When I plug in a standard barcode scanner, it behaves normally. Is there a line 
of code that causes the Error Console to pop up?

Thanks.

Do you know if the Honeywell is sending the barcode number only (i.e. integers 
only) or is it also sending some kind of barcode prefix as well when a barcode 
is scanned?

It turned out that the Honeywell scanner was sending a Line Feed in the suffix. 
This appears to be the reason as to why the Error Console in Firefox kept 
popping up. I disabled the LF Suffix and it scanned fine. 

Thank you for the quick reply.

How did you disable the LF Suffix?

You'll probably need to refer to your scanners documentation to configure it to 
send or not send particular characters.

It's in the Configuration Guide where you can use barcodes to also disable 
beeps and such. First scan "Enter/Exit Configuration Mode". Then scan "Disable 
LF Suffix" (Enable LF Suffix is on by default on the 7580 we use). Pay 
attention to the beeps to successful programming.  In my guide it's on page 8-6.
