I am not an expert on scanners. The main issue is that the contrast is set very high which makes the image appear black and white, but will also remove some of the subtlety from your mark making. That subtlety helps TAs and Uncomfortable identify mistakes in your mark making.
If you cannot find a way to lower the contrast, I suggest taking your work outside on a sunny day and photographing it with your phone. Just make sure you aren't casting a shadow over your work. If it is not possible to adjust your settings or document your work another way then continue as are.
