What causes these (constant) black stray lines on my photos? [duplicate]

Question

There are black lines on my Nikon D3100 and I'm wondering if it is a problem with the lens or with the body itself.

What method did you use to obtain the photo? Looks like it's probably dust and lint on the sensor. Try using a blower to remove it. If that isn't good enough, see What is the best way to clean the sensor on a interchangeable lens camera (mirrorless or digital SLR)? — xiota, Jan 3 '20 at 17:59

To me it seems dust on the sensor. Have you tried using the cleaning routine as described in the manual (pp.180)?
