Replacing an ADF pickup roller assembly
If your ADF has trouble picking paper, replace the ADF pickup roller assembly. See Ordering
HP parts and accessories to order an ADF pickup roller assembly. To remove the existing
assembly, follow the instructions below.
1. Turn off the device and unplug the power cord.
2. Remove the input tray and open the 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.
