@L8RDAZE Thanks for the image -- now I see the issue. @TobinLam Almost certain this would be caused by the sensor in the scanner. BTW, does anyone remember getting a FAX with strong vertical lines? If you saw that on every incoming FAX, it was a problem in your FAX machine's 'print' element. If you saw that on every FAX from a specific location, it was a problem in their FAX's image scanner. -- And remember how much fun it was to convince them to get it fixed? It was very hard to get past, "But my FAXes look OK." LOL Doing a 'copy' function to test your own FAX machine wasn't always conclusive -- you still needed an incoming FAX with/without lines to be sure. MGD
