How many tokens are in the hopper.2nd the sensor on the hopper coin counter might need cleaning. To do a reset, turn machine off turn on odds switch then turn on machine again press green button, on the inside of the door is an led light that will show 1 to 6. 1 being hardest to 6 being easiest odds Once you decide which odds you want ,press the start knob on the door front and hold it down for 10 seconds then turn off the odds toggle and machine should re boot. The green button changes the odds. I hope this helps
