There is most likely something on your scan glass that is blocking the scanner. Clean of both pieces of glass that are there when you flip open the ADF, or top cover. Try to copy again. If it is still there then there is either something on the scanner piece that moves back and forth to scan or one of your scan LEDs is burnt out and the scanner will have to be replaced.

SOURCE: HP Laserjet 3390 Prints a Black Line on papers

make sure you check and make certain there are no scratches clean both the top of the scanner and the scanner bed itself and wipe down with a lint free cloth

SOURCE: won't print black when set for plain paper

Try removing all ink bins except black then you won't have any problems. You should also be able to go into your printer settings and select "Black and White" or "No Color" and it will print ok. Removing the ink trays is the easiest way though.

This sounds as if you have some ink/contamination on the small scaning glass that sits to either the left or right of the main glass on the copier.(Depending on the model/make)As your original is scanned over this thin piece of glass the scanning device will see any spots and this will result in a black line down the page.Please clean the glass with a soft rag.
