black line appears on scan document.

[Maureen]

I am trying to scan a document on my HP F2430 all in one. Each time I scan this weird black line appears. When I print directly from the file in my computer the line does not appear, it is only when I scan the document. I have altered the scan settings many different times but still there is this weird line. usually vertical on the left hand margin. But like I said not when I print from a document on file. Anyone have any ideas?

Clean/replace the print heads...

You mean a failure of the scanner. Right? Not the printer.
The lamp array in the scanner is bad or has come loose.
HP has a number of articles dealing with that and other models of all in one printers
This one may be a starting place.

The article  has some info for the scanner. You may have to clean the glass.
