Problems you were having?
The specifications here says the minimum object distance to have a decent focus is 200mm, but it doesn’t seem the case in my tests. Attached is a shoot taken at a distance of 200mm. The numbers on the ruler are completely blurred. -

Troubleshooting attempts you’ve made?
I tried to increase the distance to 300mm, but it’s the same. The target object is out of focus. -
What help do you need?
Why this camera module isn’t able to take photo at a distance of 200mm as described in the technical specs? Could you suggest another camera model?
My goal is to have a picture of a 20x13cm paper at a distance of 100-200mm from the camera. Of course, the objects on the paper should be focused.
