Make sure if your scanning documents that the white plastic shield is on and if your scanning film this need to be removed. Make sure you also selected the proper item that you are scanning.

Hi, there are detailed instructions for replacing the battery in the LS4278 Product Reference Guide on page 27 of 414.

Use a philips screwdriver and turn the screw in the base of the scanner counter clockwise to remove the latch at the bottom of the scanner.
Turn the scanner upright to slide the battery out.
Disconnect the battery clip.
Reattach the battery clip.
Make sure the new battery is securely in well of scanner.

Login to Hotmail is easy, just like logging in to Outlook Mail because both Hotmail and Outlook Mail are Microsoft's email addresses. So the sign up Hotmail account and Outlook registration is the same.

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.

There is more setup needed and troubleshooting, please contact me so I can guide you how to get this scanner working You can always contact me by phone or email 630-622-2024 [email protected] Please visit our website www.legacyglobal.com

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.

Hi, I would be happy to assist you in resetting your LS4278, but it would be helpful to know how you are connected. The Set Defaults barcode will reset all of the scanner settings, but it will also cause you to lose the "pair" (communications) between the scanner and cradle. If you try scanning a barcode at this point you will receive a single beep followed by four error beeps. This just means the scanner is not talking to the cradle. Scan the barcode on top of the cradle. The scanner should give a high low high low series of beeps followed by a short low short high. The short low short high indicates the scanner is talking to the cradle again and you are ready to scan.

If you are connected through the USB port and scan a barcode and get one beep, but do not see data on your host try unplugging the black power supply cable from the cradle. Try scanning your barcode again and it should show up on the host.
