If you are the proud owner of a Bernina 1530 or 1630, there may come a time when your cursor no longer moves up and down, or left and right. There are typically two reasons why this might occur. The main circuit board, or “S-print” as Bernina likes to call it, may have something wrong with it, but more likely you just need to have the roller ball socket replaced.
The image to the above-right shows a roller ball socket. Click on it if you’d like to see a larger view. What you should notice is a couple of tiny axles which go through white tire-like contact points. These white “tires” are what contacts the roller ball itself. When these tires get old and damaged by contaminants and oils from your hands, then they no longer make a good contact with the roller ball itself.
Fortunately, these roller ball sockets ( Bernina part number 007515.71.00 ) are not really expensive. Installation is something that your local Bernina dealer will have to do, but should not take longer than an hour or hour and a half.
If the roller ball socket is not the problem, you will need to have your S-print sent to Bernina for repair. This can take a couple of weeks, including shipping time to and from Bernina.
