Einleitung

If you're having scanning issues as a result of a faulty sensor bar, this is where you will want to begin.

To replace the sensor bar in the Canon CanoScan N670U, you must:

  • Remove the two plastic bars that hold the glass scanner bed.
  • Set aside the scanner bed.
  • Loosen the belt from the plastic hook.
  • Remove the sensor bar for replacement.

  1. XhNXlQHfFnKCkwbV

    • Open up your Canon CanoScan N670U to an upright position.

  2. tGYJdNLeOAMXKdWD

    • Turn your device so that you're facing the long side of the Canon CanoScan N670U.

    • Locate the small crevice between the plastic components of the scanner bed and the scanner base.

  3. WORTBDusBwtN1Zwh

    • Carefully insert a metal spudger tool in the crevice and slowly cut through the adhesive between the plastic components.

    • You may cut small bits of the plastic as you're slicing the adhesive. Do not forcefully bend the plastic strip as you're cutting or it will snap.

    • Once the adhesive strip is sliced through, the plastic bar that is attached should release. Set aside the plastic bar.

  5. luGmhGyeWQQU32MT

    • Repeat steps 2-4 for the other side of the scanner.

  6. DeAyFIuCR5eENJmq

    • Use your hands or a metal spudger tool to push the plastic bar at the bottom of the glass scanner bed forward until you can't push it any farther.

  7. q3vA2WTvW1lTqSro

    • Insert the metal spudger tool underneath the glass scanner bed. The front of the scanner bed should be resting on top of the tool.

  8. 5sMfTX5AtVNfTHHc

    • Slowly pull the glass scanner bed towards you and set the piece aside.

  9. 5cx1bNJiVXrKag2Z

    • This is the sensor bar that you will replace.

    • Use tweezers to gently remove the metal spring from the plastic hook.

    • Due to the tension of the spring, it can be difficult to pull the metal end. You may attempt to use your hands to pull the spring itself if necessary.

    • Take caution to not bend the metal.
