LSU needs good internal cleaning. If no improvement, may need to replace each of the LSU which are having this issue.

The mirror faces on the laser polygon mirror become dirty in certain environments and it happens unevenly and to one end due to the rotation. See pic

Yes, this was problem as well, thanks' What I found wierd was, that normal prints and printing Status page had this problem, but Service status page from maintenence mode was fine.
And btw there is bulletin "2N4-0032 (F048)" which basically says that you should stick some tape around the plastic covers of each LSU unit.
