I also have a Jet 16-32. I am not understanding exactly what your problem is. Did you mistype the word lower. To me a ridge is a high spot. I know it makes sense to you. I have tried to explain problems to other people, that are very clear to me, but the other person just doesn’t understand. Can you send a photo (or a drawing) possibly highlighting the ridge or areas with chalk or a pencil. Click on img above the area where your are typing to send a photo. Also how long are the boards? Is this drum sander new to you? Here are several things that I would check or do.

Is the sandpaper on you drum clean.
Is there and dust accumulated between the sandpaper and the drum.
Is the tension clamp keeping you paper tight.
Is there a bow in your board.
If you have an infeed table check it to make sure it is not creating the problem. It may be set too high. I don’t use an infeed table on mine because I sand a lot of long boards and if one has a bow there is a problem.
As mentioned above take light passes. I consider a 1/8 turn or less of the adjuster a light pass.
Draw white chalk lines across your board before sanding and you will see exactly where the sander is sanding.
Change your sandpaper.
What grit are you using?

Keep sending more information and someone here, will have the answer.
