I don't think that's a job for the frontend (XSane). The backend should provide an option to adjust brightness/threshold for Lineart as usually the variable threshold value is implemented in the scanner's hardware. If the backend supports Lineart, it should allow to set a threshold. Maybe you have disabled standard or advanced options in XSane?
