New to Java

Hi, I'm supposed to be writing a program that changes the state of a machine according to the inputs that it received, I decided to use switch statments to read the input and produce the output from it. When I compile I get the error message

"Controller.java:103: orphaned case
case COPY:
1 error"

I vaguely understand the concept of an orphaned case but can't see what Ive done wrong. Please help!

public class Controller {

 static public void  main(String[] args) {
  //MASKS
  final byte ON_SWITCH = (byte)0x01;
  final byte CARD_IN_OUT = (byte)0x03;

  final byte RESET = (byte)0x00;

  //OUTPUTS
  final byte NO_LIGHTS = (byte)0xff;
  final byte ON_LED = (byte)0xfe;
  final byte ON_CARD_LED = (byte)0xfc;
  final byte ON_ERROR_LED = (byte)0xf6;
  final byte ON_CARD_ERROR_LED = (byte)0xf4;
  final byte ON_CARD_COPY = (byte)0xf8;
  final byte COPY_25_LED = (byte)0x74;
  final byte COPY_50_LED = (byte)0xb4;
  final byte COPY_75_LED = (byte)0xd4;
  final byte COPY_100_LED = (byte)0xe4;

  //STATES
