Launch the EZ Scan software, connect the USB cable to your PC and the scanner. The scanner must be off. Click
on the Scanner/SD card tab and select Prepare Scanner Memory/SD Card for Use. Check ALL THREE boxes. Confirm the correct drive is highlighted, click FORMAT. At the prompt, press ENTER and follow the prompts.
The same process works and is faster if you have an SD Card reader on your PC. When done, click CLOSE, reinstall the SD card if using a card reader. Power up the scanner. If you stored your programming data in the EZ Scan software everything is up and running again. If you never saved it to the PC, then your scanner is restored to factory defaults and is ready to program again.
