Scanned documents printing very dark

[siawacsh]

Hi, I have a Samsung ML-1675 with  driver2 1.00.39 driver on Linux Mint 18.3 64 bit.

I am finding every document that I scan in prints too dark. Other documents are fine.

My scanner is the Cannon 200 Lide using Simple Scan

I have tried playing around with simple scan brightness, contrast and quality settings which has not helped much.

I cannot see anything under system administration for scanners.

Can anyone help with that?

Thank you.
