You don't need a smart phone to put pics here. Just a digital camera that you can download the pics to your computer with. Then it's easy to follow the prompts here to put the pics in. Your machine is probably one of zillions of Japanese made ZZ machines. It will most likely have two power cords on it. One for the motor and one for the light. If it has it's case there is probably a compartment on the right end of the case where the cord block was originally mounted. These cord blocks, the foot controller, and some top tension springs are available from Sew-Classic {
