Is losing sharpness at higher DPI normal?

Hi all, would like some advice on an issue I'm facing. Was scanning some rolls for the first time and noticed there's a stark difference between DPI 600 and anything above that. The moment I leave the lowest DPI, my images look too soft for what they are worth. Initially I chalked it up to misfocusing or user error, but it seems that it's pretty good at DPI 600. However, I didn't buy a scanner to use it at the lowest setting.

Anyone else faces this issue? Would love some comments and will post photos once I can. The scanner is a canon 9000F and is brand new.

Some scanners use software extrapolation for higher DPIs. You might want to check with Canon Support.

Scanner Features and Definitions - Resolution

Read the section on 2400 dpi flatbeds. It seems this is a problem with flatbed scanners.
