Here's one of the ways I go about it.
Manually knit stitch back to NW Position
Remove pegs making sure that ribber comb drops in front of the gate pegs.
Hold comb firmly downwards and pull forwards so that stitches are pulled back to working position. ( You have large loose sts and ribber comb hanging lower down.)
Knit a few rows with waste yarn, bring all required needles to working position and knit a couple more rows waste yarn.
Knit 1 row nylon cord and continue to knit with main yarn.
There is also a quicker method using the ribbers sinker plate but you need to be very confident with your knitting machine and is not suitable for beginners.
