Help Please: Canon Pixima MG3200 Printer/Scanner , simple-scan scans poorly

[kissbaby3]

Simple Scan can be made to work better via Document > Preferences: Increase dpi Resolution(s), set Quality to max.
With presets only the results may well be mediocre.

i made a video showing the settings and other things, on "simple Scan" , this version of simple scan might look different at your end , at my end , on simple scan, there are 2 settings for resolution, just watch the video .

my printer and scanner does well on my windows 10 "back up" pc upstairs .
on linux , printing stuff from the web and other things is fine, so the printer works fine , its just when it scans  a image/document , it again scans poor visual quality and prints the scanned image/document poorly, looks faded and washed out.

after watching the video , what settings should i try ? , i did play with simple scan some, but i am perplexed as to why it does poorly now , when a few months ago it did well.
