Laser is Not Centered

If you cannot see your Laser or it is dim, follow the instruction in the Dim Or Completely Out article. If your Laser is not centered to the Needle Plate hole, follow the steps below.

WARNING!! DO NOT allow the laser beam to be aimed at yours or anyone else’s eyes. The laser emits a very concentrated light beam that can cause permanent blindness. Use extreme care in handling the laser assembly to make sure it is not going to be inadvertently aimed at someone’s eyes or face. DO NOT LOOK DIRECTLY AT THE LASER LENS WHILE IT IS ENERGIZED!

1.  If you are sewing Caps, or any fabric that is raised up from the Needle Plate, push down on the fabric until it touches the Needle Plate while you do your Laser Alignment. The higher a fabric sits from the Needle Plate, the less accurate the laser will be.

 2.  To make sure the laser is centered correctly, place a piece of paper covering half of the hole in the Needle Plate to see if the laser is going through the hole.
