@steve1945 there is no reset button per se. You can reset your printer by following this:

1) Turn the printer off

2) Press and hold the STOP button for 3 seconds.

3) Then press the ON button and release the STOP button.

4) While holding the ON button, press the STOP button 5 times.

5) Release all buttons.

6) LCD Screen should turn on and be blank. After a minute or better turn the printer off once more.

This should be the reset. Now I am wondering why you've asked.....
