My product displays an error after I connect a USB memory device to it. What should I do?

• Make sure the USB memory device meets the printer's specifications, that it is properly formatted, and that it is not corrupt.

  To clear the error, turn off the printer, remove the USB memory device from the printer, then turn the printer back on.
