Poor M234dw scan quality

[PaulAndTheBrain]

Hey,

have you faced the below poor scan quality with LaserJet MFP M234dw?

Is it normal? No matter if I pick 300 or 600 DPI it's the same.
The picture is zoomed in a bit but this background color should be pretty SOLID.

What do you think? Normal for this device or should be better and something's wrong?

I've updated the firmware. It's a bit better.

I'm attachining the scanned document after the update.

Does it look acceptable?

To me it's not perfect as for 600DPI.
