Re: Scanner does not scan. It seems to be jammed, stuck.
It's dead simple to clear the jam. If you already bought a new scanner, you can fix the Canoscan and sell it.
OK, first how did it get jammed in the first place? Probably because you moved the scanner without closing the lock on the bottom. The scanner arm then got jogged out of the home position.
There are two ways to go.
1) Reverse the impact that caused the jam. To check if this is feasible open the top of the scanner. If the arm is not tight against the front (where the 3 black buttons are located) then this might work. Get a cushion that is not too thick and place it on your desk. Holding the scanner in both hands stand it on end so the front edge is down and the back edge is up. Look at the back to make sure the lock is open, then tap the front edge of the scanner firmly against the cushion. Set it down and open the cover to see if the arm is now tight against the front. If not repeat two more times tapping a little harder.
If this seems to work, test if the scanner arm is in the home position. Turn to the back of the scanner and try to close the lock. If the scanner both looks like it is in the home position and you can lock the arm, then it is probably in the home position.
If this seems to work, unlock the arm of the scanner, connect to your computer and test it.
2) If this method does not work it's time for a little open scanner surgery. Open the lid of the scanner and observe the cable that runs from the front to the back. It is just a cord about 1/10 inch (3 mm) thick. Observe where it meets the back of the scanner.
Close the lid and stand the scanner on its front edge. You will see an oval patch slightly darker than the panel. Use a penknife to lift the edge and carefully peel this off and save it. You will observe a hole with a slot shaped like the letter Q, the slot being the tail of the Q. This slot keeps the cord in place. You must plug the hole befoe proceeding further to ensure that the cord does not slip out of the slot. (Mine did and it took me half an hour to figure out how to reassemble the moving parts.) Use a twig, tapered pencit stub or a wooden chopstick as a plug.
Now set the scanner on the desk, open the lid and locate the two oval plastic patches at the left and right front corners. These cannot be peeled off because they are part of the frame that secures the glass plate. You need to lift each oval patch with your penknife. First slip the penknife into the crack on the right side of the scanner just a little back of the oval patch and lift the patch. Gently wiggle the knife and slide it back to lift the whole right side of the frame. Be especially careful not to lift near the back end because there is a little lip that goes under the back side of the frame. Repeat with the left side, which is a little more difficolt to get loose. Do not try to lift off the front or back sides of the frame.
Now you are ready to remove the glass plate. Slide your penknife in the gap at the front of the plate and nudge it to the back. Gently pry up the front edge of the plate and lift it up about 4 inches (10 cm). You may be able to push the arm into the home position without completely removing the glass plate. If not, pull the glass plate forward and lift it off. You may need to wiggle it a little to get it loose. Gently push the arm to the home postion at the front edge.
To test if the scanner arm is in the home position, reach under the scanner and try to close the lock. If you can lock the arm, then it is in the home position.
Don not turn the scanner over to see the lock. This would cause the whole assembly to fall onto your desk.
Reassemble the scanner in reverse order. Unlock the arm of the scanner, connect to your computer and test it.

It is normal for this scanner to briefly "scan" when it is plugged in. However, the moving lens shouldn't go all the way down to the back end. It sounds like the scanner is physically damaged, most likely the belt slipped several cogs and now the scanning mechanism is out of alignment. Look into warranty service for the unit.
Does the message shows after few pages scanning or is there any
panel error message like J-1 on scanner start up?
If the issue
occurs during scanner start up, then there are staple pins or dirt might
be stuck inside the US Sensor panel inside the scanner. Cleaning and
removing the objects will resolve the issue.
If the error occurs
after few pages scanning, then you may have to check the Pick Roller,
Brake Roller, Pinch Roller and US Sensor FX status. you may have to
replace any of the above, if damaged or worn off.
Hope the above
information is helpful.

There are a couple possibilities that can cause the problem.
1. you need to unlock the scanner. There is a lock at the side of the scanner that could be in the locked position which is preventing the scanner from moving. you can use a nickel or penny or screwdriver to turn it to release it.
2. the tab that is holding the gear is broken 3. the glass is not attached 100% to the upper case and the scanner is hitting it when trying to scan. if its 2 or 3, you might be better off getting a replacement.
If you are receiving an Error Code 103 or a Paper Jam error,
but there are no pages in the ADF (Automatic Document Feeder), follow
the steps below:
Close the scanning application (such as PaperPort)
Turn off the scanner and the computer
If you have a combination ADF with a Flatbed scanner, unplug the ADF cable from the base of the scanner
Plug the ADF cable back in
Turn on the scanner power
Turn on the computer
Try scanning again
For a Paper Jam or Error Code 103, make sure that the ADF cable in
the rear is connected to the scanner base. Check the flatbed to make
sure that it is clear. A page incorrectly placed on the flatbed may
interfere with a page feeding through the ADF.
If your scanner stops scanning due to a paper jam in the Automatic
Document Feeder (ADF), a warning dialog box appears after a few moments.
To clear a paper jam:
Open the Automatic Document Feeder cover.
Remove the jammed paper and close the cover.
If you are receiving a paper jam error, or if the scanner is
running continuously, check to make sure the paper sensor arm is not
Open the Automatic Document Feeder cover.
Look for the small black plastic arm
When you press on this arm, it should move freely up and down
If the arm is stuck down, please contact Technical Support for troubleshooting options
I finally solved my problem. Now it works like new.
- The spring that returns the next sheet detector (small black plastic rocker arm between the two rollers on the back side) came off. So the scanner cannot detect transition from one page to the next. This spring is located inside the device and you cannot fix it from the outside. - You know if you have this problem if you don't hear a "click" sound after each page is scanned. Without the spring attached the rocker will not return on every page. When it doesn't return the scanner think it is still on the first page and will not scan the next page. The "click" after each page is NORMAL. Without the click is the first sign your spring came off.
Solution (Only recommended for people handy with hardware and the unit is no longer under warranty)
1. Turn off power and unplug the device. 2. Pop off the plastic cover to the back of the scanner 3. Remove the screws that holds the plastic cover to the back. 4. Remove the screw by pushing on the retainer clips. DO NOT loosen any gears or motors. 5. Locate the rocker arm and re-connect the (very small) spring
6. Warning - if the LED light pipe falls out be careful how you put it back. This is a transparent widget at the top to route a LED light to the top of the device to indicate the power on status.
Sorry I didn't take pictures. If this sounds too complicated, send it to Canon for repair. Took me about a day to figure out exactly what was wrong and how to disassemble the scanner to fix it.
Sounds like the lock-switch is in the locked position. This is on the bottom of the scanner. Move the lock-switch back and forth a few times and then leave it in the unlock posotion. Try scanning again.
If you are scanning a book, it may be too heavy and putting enough pressure on the scanner that it is preventing the scan head from moving fully. Try scanning with nothing on the glass to see if it does the same thing.
This type of issue could be related to different sources. First step I would do is check to see if the lamp is coming on within the scanner, possible bad lamp. One other possibility would be the CCD failure, it may not be moving across to capature your film. Also, when attempting to scan does the scanner sound normal or abnormal. If abnornal sound is occurring then CCD could jammed/stuck hardware failure. Last step would be uninstalling/reinstalling your scanner software, check for updated drivers from the manufacture of your scanner. At this point if none of these suggestions helped then test scanner on a different computer system.
