Hi,
good luck trying to get an even print just using black. Having said that though you should be getting a better output than that.
By looking at your sample it appears that your Black drum might need replacing. I would also try printing the job in a Line screen.

Hello,
The revealing black unit is new, and it just happens to use thick paper (240 grams or more) and quietly, if dark is normal.

Paper Setting -> Choose the tray where the paper is -> Change -> Process Adj. -> Set "Separation DC Front" and "Separation DC Back" to -30 and see if it improves.
