No reverse or backing
The JUKI DDL-7000A-7 Series sewing machine has a function setting (P139) that controls reverse feed stitching. If the reverse feed stitching function is not enabled (set to 0), the machine will not perform reverse or backing stitches. To enable reverse stitching, the function must be set to 1, which allows reverse feed stitching when the reverse switch is pressed.
