There are three possibilities I can think of assuming this is not a brand new scanner:

1. The LS4278 is faulty - which given Symbols quality I would say it is normally not the case unless th scanner has been dropped or otherwise damaged.

2. The cradle is not charging the scanner. You may wish to try another cradle - one that you know is charging aother scanner. After a few minutes you should be able to see the laser.

3. The battery in the scanner either needs a recondition (see product reference guide), or needs replacement.

My canner ls4278 is making a sound and turnin red when i scan


It could be the scanner is not paired to the cradle. The scanner will be once for the barcode and then four times for the communication error. Make sure the cradle has power; it will pull power from a USB port. Scan the pairing barcode on top of the cradle. The scanner will give a high low high low beep and then shortly after give a short low short high beep indicating the radios have paired. If the scanner still beeps four times after doing this, the host type may not be set. If connecting USB scan HID Keyboard from the LS4278 Product Reference Guide.

I have a symbol LS4278 scan gun. When I place the gun in the cradle it blinks with an amber light. In the documentation that says that it has a "Critical battery temperature fault". I replaced the...


Hello Lynda,
this seems to be an error with the charging system of the scanner. As you stated the error occurs also with other battery. Just check if the scanner is in warranty and send it for repair.
It could work also with this error, but the charging will not work correctly. As the temperature error is safety measure which stops the charging until the status get changed.

I have a new LS4278. I need to congigure it to read fedex barcode


All you have to do is create a rule to transmit only the 12 digits you want.
You can create a rule with the Programming manual or the 123scan software.
Both of these are available online at support.symbol.com. Here is a short cut:

LS4278 scanner can't read digits


Hi, try scanning French Windows barcode from the USB section of the LS4278 Product Reference Guide. The barcode is on Adobe page 147 of 414. You may also have to scan the Enable Keypad Emulation barcode from Adobe page 150 of 414, but I would do this only after testing with the French Windows setting first. I suggest saving a copy of the document before printing the barcodes just to make it easier to print. Hopefully this will resolve the issue.

How can you use a symbol model ls4278 with a usb converter for the ps/2 plug?


The scanner will probably give you error beeps because you are not using a PS/2 keyboard. All you should have to do is scan the IBM AT Notebook barcode from the LS4278 Product Reference Guide. The link below will take you to the manual and the barcode is on Adobe page 104 of 418. I would suggest saving a copy then printing just the page you need.

If the scanner does not start working immediately you should reboot your computer.

LS4278 makes the same beep with a valid code vs an invalid code


Contact the Symbol Help-desk at 1-800-653-5350. What you are asking is not possible with the LS4278. What you are probably hearing at the grocery store is the cash register software generating an error beep. The LS4278 is really just a simple scanner( eben though it is cordless) but it has no memory, and therefore cannot be loaded with a database for error correction. That is being generated by the software at the store, not thye scanner itself. For clarification, uyou can call me at the office:
