assembly
To change the ADF pickup roller assembly
If your automatic document feeder (ADF) has trouble feeding paper, you can replace the
ADF pickup roller assembly. See
Accessories and ordering information 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. 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 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.
