Swf 1501c

I removed the s/s rollers on the head to clean, free up and lubricate them so they would glide; however somehow when I put them back in, I got the embroidery head out of sync with the computer and I am not quite sure how to get them back together. Does anyone have any suggestions....please do not bash SWF, we all have our opinions, I am looking for honest assistance in getting this resolved.

Thank you!

remove the screws holding the color change motor on and pull the motor away from the head .Set the head aligning the needle three over the needle plate then turn on the machine press three on the control panel the motor should rotate put the motor back .

Or remove the head press three to get the motor back to the right spot then put the head back on (this is tricky if you have not done it before)
