Detach the ADF assembly. Remove the 4 case screws from the scanner bottom. The case has a notch at the back that has to be unclipped to separate the top and bottom. Clean the glass underside repeatedly, I use methylated spirits on soft toilet roll. Check in the glare of the scanner light, and reassemble.
I have many years repairing Canon scanners and here is my suggestion to you.
If you are positive the lock switch is unlocked then I think what happened is the scanner inside the scanner is off its track an can not move. I would remove the glass on the top of your flat bed scanner to gain access to the scanner lens then I would try and move the scanner lens manually with the power off to the scanner. If it does move freely then I would think you have a bad scanner lens. If it doesnt move freely try and reposition the lens back on to its track. They some times jump off there track from shipping.
Open up your scanner's lid. It does not matter if the scanner is on or off for this basic, regular cleaning.
Wipe down the glass surface with a dry, lint-free microfiber cloth. This will remove any dust or other fine particles that have accumulated on the scanner. You should remove excess dust every day or two.
Scan a blank sheet of white paper into your computer and look for visible discoloration. A white sheet will provide a clean, blank slate to view the scanner's overall quality. If you notice any irregularities on the white sheet, you need to do more thorough, semi-regular cleaning.
Turn off the scanner and open up the lid.
Spray a small amount of "mild glass cleaner" on a soft, clean cloth as recommended by Scanner-Magic.com.
Wipe the scanner's glass to thoroughly clean the area. You should perform this semi-regular cleaning at least every two weeks or sooner if a white sheet of paper indicates discoloration.
Keep the scanner's lid open for a few minutes until all excess glass cleaner has dried.
This is acutally easier than it looks. I just had the same problem with a cloudy film starting to form underneath the glass on my older HP 4400C scanner.
First completely remove the hinged top lid by lifting straight up on both long ends of the lid - notice the 2 hinges on the back end of the lid will come straight up and out of the body of the scanner, still attached to the lid.
Next look down inside the 2 hinge holes (on the main body of the scanner where the lid hinges just came out of) and you will see a screw in each hole. Remove both screws using a phillips screwdriver. This will allow the rear end of the scanner to come apart enough so you can now lift it up a few inches to separate it and get your hand inside there to clean the underside of the glass with a soft cloth - BUT JUST REMEMBER THE FRONT END OF THE SCANNER WILL STILL BE CONNECTED, so don't pull it too far apart because it could snap and break something that is still holding the front end together. (I could not figure out how to separate the front end piece, and then I realized I didn't have to).
So on the rear end of the scanner, now carefully pull the light upper colored plastic apart from the lower dark plastic just enough so you can get your hand inside the compartment and use a soft cloth to clean the underside of the glass. I just used a small piece of an old cotton t-shirt with a couple little dabs of water on it and then just kept rubbing the dirty areas on the underside of the glass over and over until all the dust film/streaks disappeared and the glass was once again clean and all clear.
Then gently lower the glass back down and line up the plastic pieces together on the rear end and put the 2 screws back in the hinge holes, and then reinsert the hinges in their slots and lower the lid back on top of the scanner glass and it is ready to go again !!
To open the Canoscan 8600 to clean the inside of the glass: Gently pry off the silver "c-shaped" trim piece on the front of the scanner. Slide the silver trim pieces on each side of the scanner forward and remove them. Gently pry off the remaining black trim piece on the front of the unit. This exposes 3 phillips head screws at the front of the scanner. Remove them.Pull straight up on the rear lid of scanner (where the 2 hinges are) to remove the top. This exposes 2 screws at the bottoms of the wells that secure the hinges. Remove them.Now the top is held by only 2 clips - 1 on each side.Pull up gently on the left side of the panel, front and back, and slide the panel back towards the rear. That should free the clip.Repeat for the right side.Take it easy, and you won't break anything.
Found this question on-line as I also wanted to know the answer. Couldnt find an answer so I just decided to have a go myself. It was quite easy really.
Lift the lid upwards and gently push it backwards from the hinged end and it will unclip.
With the scanner facing away from you, undo the only 2 screws visible at the back. Then gently lift up and push forward towards the front. You can see thru the glass 3 plasic lugs holding the front down. With a little wiggle the cover with the glass attached will come away from the slotted holes where the plastic lugs go. Clean glass an carefully replace lid in the reverse order.
The 3170 has a screw in each of the two slots where the lid inserts into the scanner. Remove the lid, remove these screws, and then the top portion of the scanner with the glass slides forward and off. Mine was stiff getting it off, but with some slight twisting and a bit of force it came off. You can then clean the glass.
I would not worry about the underside of the glass unless you are having problems. The focal length of the ccd that captures the image is very specific and probably will not pick up anything under the glass. It is normal for the underside to look foggy but it will not hurt anything.
remove the lid by lifting up. There are two philips head screws exposed. Remove screws and lift top of scanner off. Pay particular attention to thumb wheel position when lifting. Go to computer repair center and buy double sided tape. replace tape and reverse process
