1. Verify the Brother device is plugged into the AC outlet and the power is on.
2. Look at the LCD/LED on the Brother device and confirm it is not displaying an error message.
3. Make sure the cable is connected from the Brother unit directly to the computer. The cable must not go through another peripheral device (such as a Zip Drive, External CD-ROM Drive, or Switch Box).
4. Check that the cable is not damaged or broken and is no longer than 6 feet (2 m) in length.
5. Verify you are using a Hi-Speed USB 2.0 certified cable if your computer uses a Hi-Speed USB 2.0 interface.
6. Confirm the appropriate printer driver is selected. For example, if printing from MS Word, click FILE on the menu bar, click PRINT and make sure the Brother device is listed as the default printer.
7. Make sure no other device drivers, such as Zip Drives, External CD-ROM Drives, etc., are set to run automatically through the USB port when booting up your computer.

Suggested areas to check:

• Win.ini file - to see this file please refer to C\WINDOWS\Win.ini.  If you can find any devices which communicate with the USB port listed with load= or run=, you need to delete them.
• Startup Group - please click Start -->Programs-->Startup.  If you can find any devices which communicate with the USB port, you need to delete them from here.

If you still have the same problem, contact Brother Customer Service.
