Procedure 1: Operation check for the lower side of the shield detection feeler

  1. Place the fusing unit on a flat place and tilt it towards the drawer connector [A].
  2. Move the shield drive gear with your hands to put the upper surface of the feeler [A] in a horizontal position.
    • It is necessary to move the gear to move the feeler.
    • Moving the feeler directly will affect smooth operation, so be sure to move the gear.

  3. Keep your fingers off the shield drive gear.
  4. Make sure that the shield detection feeler [A] moves down to the lowest point by its own weight.

    • The feeler moves smoothly: OK
    • The feeler does not move / stops during moving / moves slowly: NG

Procedure 2: Operation check for the upper side of the shield detection feeler

  1. Place the fusing unit on a flat place with the drawer connector [A] turned up and the handle [B] touching a flat surface.
  2. Move the shield drive gear with your hands to put the upper surface of the feeler [A] in a vertical position.
    • It is necessary to move the gear to move the feeler.
    • Moving the feeler directly will affect smooth operation, so be sure to move the gear.

  3. Keep your fingers off of the shield drive gear.
  4. Make sure that the shield detection feeler [A] moves up to the highest point by its own weight.

    • The feeler moves smoothly: OK
    • The feeler does not move / stops during moving / moves slowly: NG

Results

  • Both Procedure 1 and 2 are OK: No problem.
  • Either Procedure 1 or 2 is NG: The mechanism is blocked.
  • The shield detection feeler never moves while moving the shield drive gear by hands or fingers: Locked.
