07-00-10 error code refers to a drop out voltage warning, basically this means something in the machine is shorting the power supply out, the chance's are that the fault lies with the trailing cable where the laquer and white coating eventually wears down to reveal bare trailing cable connections which short to ground causing the power supply to temporarily shut down causing the formatter to display the error. this is a very old model now and the chances of you being abble to order 'new' have allready gone. I would recommend upgrading to a newer model.
