"prints are fine"

How are the scans looking in different settings?
Did you print some grayscale test print, too? Sometimes you can get decent solids but bad half tones. Copies usually don't use 255 solids due to dynamics limitations.

I've had issues like that with "appearently" fine prints.

I've also seen issues with bad gradation adjustments - try and delete the gradation adjust and don't calibrate it again but check if the copies look better.
Last resort: machine inititialisaion (after USB backup)

which initialization are you speaking of?

I belive he's talking about under Image Process>Stabilizer>Initialize+Stabilization. Then run gradation

If that doesn't work last resort system 1 in service mode > initialization > clear all data

Can you please share the copy and print for comparison?

I also agree with the initialization. You should give it a try. Then firmware update.
