The HP LaserJet 2430 printer departure black smudge lines 2" in from moreover edge. Cleaning process followed but to no advantage. It is unexpectedly departure a black smudge down the middle of the page. It is an asymmetrical pattern, though it seems that it is darkest each 1 1/2 inches so that makes me imagine it is a number of cylindrical roller that is smudging the toner. Any suggestion regarding where to start.
