Replace the switch. A trick can be done here. Unplug it then spray the switch (Soaked) with warm distilled water with mild soap. then let it dry using a Hair Dryer. Then test!

SOURCE: Canon 9950F has lines vertically
Although the problem sounds like a defective CCD, which is not repairable, I would strongly suggest you take the unit back apart and clean it again.
Because one single speck of dust on the mirrors will cause a vertical line like the one you speak of.
Here is a trick I use to clean the optics on copiers:
1) Get a low lint rag or shop towel NOT a paper towel, tissue, etc
2) Get a bottle of Windex. The stuff with ammonia works better on optics.
3) Spray the Windex on a corner of the rag. Make sure it is very damp.
4) Clean the mirrors/optics horizontally from side-to-side, making sure to get the corners.
5) Use the dry portion of your rag to soak up any residue. Once again, go side to side, not up and down.
6) Shine a flashlight on the optics and make sure there is not a single smudge or speck of dust. If there is, go back to step 4.
Also make sure to clean both sides of the glass.
Good luck! If my answer helped you, please rate me and comment. If not, please follow up with me. Thanks!

Testimonial: "Thanks, I did as you recommended but i blieve it is the CCD. Is there a place to buy one?"
What operating system do you have? Go to the Canon support site:
Use the drop down menu to pick your OS (Mac or Windows excluding Win7) Win7 may work with the Vista driver (I am not sure of this) or a native (in Win7) driver for a TWAIN compliant scanner may work. The above URL also includes links to the manual and quick start guide. Install the software, unlock the scanner (transport lock is near the hinge of the lid towards the right of center). Connect the power, USB and FAU cables to the scanner and plug in the power to the outlet and the USB to the computer. Turn on the scanner and see if you can scan.
If you do have Win7 and have to use the Win7 drivers, you will not be able to use the buttons on the scanner to start the scan. You will be able to scan using Windows Fax and Scan (New scan) or Paint (File > Import from camera or scanner).
I hope this helps.
