Cindy You have two optical sensors behind the needle case. As you are looking at the needle case one is located behind the right side of the case about half way up from the bottom. It's purpose is to see the flag that protrudes from the black cover behind the needle case. If it doesn't see the flag the machine will continue to move to the right until it finds it. Once you find the optical sensor, try blowing any lint or dust off of it. Also check to see that the sensor is not rubbing on the flag which is part of the black cover directly behind the needle case. The flag should be centered inside of the sensor but not touching it. Go into your maintenance menu and the go to Steppers and select "Home"under color change. The needle case should go to needle #9. If the needle case goes all the way over past #1 again you may have to put in for a service call Hopes this helps. Hugo Torbidoni H T Embroidery Repair Harpers Ferry WV 304-724-8846
