This problem just started and I have no idea how to fix it. A vertical line sppears every time I scan an image. I have
cleaned the glass and the bottom of the scanner cover. I have also unplugged everything and tried scanning again, but
the problem still persists. I tried troubleshooting online, but I cannot find a remedy for my specific product. Most of
the solutions I find seem to be telling me to pull the scanner apart and clean the strips and what have you, but I'm not
sure my scanner can even be taken apart like that. I have an HP Deskjet F4480 and here's a sample of what happens when I
scan, note the straight line going down the scan to the left.
