    • The metal 'spine' you are going to re-shape is under the grey plastic rail with the 'cog teeth' that you can see inside the scanner.

    • Firstly turn over the scanner and remove the 3 screws on the back of your scanner which are covered by plastic dark grey oval strips (2 at extremes, 1 in center; the 2 covers in between these can be ignored). This is so you don't have to turn the scanner over latter when parts may fall out. These screws hold the metal 'spine' in place.

    • To get to the 'spine', you must first gently lift off the two plastic strips that run on the long edges of the glass.

    • Use a knife to prise them up, they are glued down, and have plastic clips on the outside that allow them to slide towards the rear (USB end) of the scanner once the glue is up.

    • Alternate method: The ends near the hinge are not glued and have a tab that slides under the back edge. You can bend each strip up with a knife near the hinge, and slip the tab from underneath the back edge. The strip then lies on top of the back edge.

    • Next prise up the glass from the front (buttons end) of the scanner at both edges.

    • Alternate Method: After getting the side strips on top of the back edge, you can slide the glass plate towards the hinge to undo the locks on the side. At the front, near the buttons, you can pry the glass plate up, then pull it forward and remove it.

    • At this point you can test again to see if the scanner back is bowed by pressing the casing in the centre of the base with your fingers to see if it dips towards the table/surface it is on.

    • 4. Then undo the three screws on the rail. You can lift out the metal rail. Place it on a flat surface to see if it is bowed, and if so, gently bend it flat.

Smooth Guide! I had exactly the problem described here and thought that I had to part with my dear scanner. But thanks to these instructions he is back in action, as good as new! Thank you so much!

I had a problem where the scanner made a horrible noise, but the metal rail did not seem to be bent. I opened up the scanner according to this guide, reseated the scanning head, closed it, and it worked smoothly again. Thanks.

By doing this, I found out that it is not necessary to undo the glue of the side strips. I inserted two steps in the guide to explain this (sorry, no pictures).

Thank you so much! I was in the middle of a project, scanning some of my quartet/quintet music into pdfs so I didn't have to cart my music all over with me--just a thumb drive! My well-intentioned 6 year-old wanted to help and the scanner was knocked off the table. Oops! The metal last was bent and the scan bar was jammed at the top. I sat in a coffee shop and fixed it. Thank you, thank you, thank you!

Fixed my Canon LIDE 25 with the help of this manual.

There are only 2 screws with our machine. First remove the 2 screws (covered by the stickers in the back - yes the round circles are stickers)

Then turn over, carefully remove the plastic on both sides with a sharp knife (they are glued). Afterwards the glass comes out by pushing in a bit and lifting out.

Now place the middle rod in its grooves with a small pin midway that goes into a small hole. (if the scanner head is in the beginning push it a bit)

Then carefully place the two screws back. Run a test scan to see the head is OK. Then place the glass back by placing at the end first and when inside the end turn the scanner upside down and slide the glass to the end. turn over pull the glass a bit to the front. return the two plastics on the side that were glued (the glue is sticky and still good).

Hope this can help somebody.
