The easiest improvement to make would be to use "Fine" mode at a minimum to bring the vertical resolution up to 200 DPI. If a higher resolution is available (e.g. "super fine") that would be even better. The corner marks on the form are clearly designed to help with form processing, so I'd use them in your image processing pipeline to deskew, remove background printing, etc. The form can be broken into zones to be recognized individually, using knowledge of the type of information expected to help tune things.
