If you get a "Color Change Timeout" error message on your TC-1501 embroidery machine, follow these steps to solve the issue:
To begin, make sure your machine is at 100° by manually rotating the Black Knob on the far right side of the machine. Rotate it 1-2 full times just to be sure.

Then confirm whether ALL of the take-up levers are the same height.
If one of them is popped down, you can pop it back up manually. After this, the issue should go away.
If one of them is popped up, there's a quick adjustment you can make by following the instructions in this video: Take-Up Lever Adjustment
