Question about Brother MFC 7420 All-In-One Laser Printer
If it's a thin, sharp line, it's just a blob of ball-point pen ink on the scanner glass. Lift the lid, and you'll see the narrow strip of glass that the scanner uses when you feed a document through the feeder. Clean that with a rag dampened with window cleaner, or, better yet, alcohol. Even a dot of ink too small to see will show as a solid black line on anything you copy, scan, or fax via the doc. feeder.
Don't use so much cleaner that it runs under the glass.
