ID: 50266

Description: Please remove the power and the USB cable...

Steps:

1. Remove the Power- and USB-Cable!
2. Remove the paper tray that contains the paper completely.
3. Open the front cover and remove the screw on the left side.
4. Turn around the printer and open the back cover.

5. Hang out the back cover: After opening it, you can start to hang it out. Press from the left parts ro the right and move it towards yourself.
6. Please remove the Screw on the right side, as shown in the image. If you want to remove the Automated Document Feed (ADF) you might now remove this screw as well.

7. To remove the cover from the side where the internal cables are pluged in and the motherboard is located, follow these steps:
8. Raise the upper cover (not the automated document feed). I mean the cover benath the scanner glas.
9. Now turn the side to you, where you've already removed the screws from.
10. The side cover is held by some Hooks, so it can be a bit tricky. Start from the right ro remove the cover. Lift up the darker grey plastic parts slightly.

11. After you fully removed the cover, you'll have a view on the motherboard, the cable and the plugs.

12. To change or remove the ADF-Scanner-Unit, you'll have to remove the cables I've marked in the first picture.
13. On the back side remove the screw at the right ADF-hinge.
14. Pull out the cable carefully.

15. Open the scanner glas area and be carefull that the ADF falls not down on the left side. It could break the hinge on the other side.
16. Now remove the screw on the inner side of the right hinge. Please take care to use a screwdriver with the correct screwsize. Here it could be tricky otherwise.
17. Now you can remove or change the ADF.
