Replacing the automatic document feeder (ADF) pickup roller assembly

If your automatic document feeder (ADF) has trouble feeding paper, you can replace the ADF pickup roller assembly. See Ordering hp parts and accessories to order an ADF pickup roller assembly. To remove the existing assembly, use the following procedure:

1. Turn off the device and unplug the power cord.

2. Remove the input tray and open the automatic document feeder (ADF) cover.

3.Press the round green button while lifting the green lever. Rotate the green lever until it stops in the open position. The old pickup roller assembly should remain on the black surface.

4.Remove the old assembly and put the new one in exactly the same place. The largest roller goes in back, and the gear side is away from you.
