Changing an ADF pickup roller assembly
If your ADF has trouble picking paper, you may want to 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 directions below.
1 Unplug the power cord from the printer.
Note
If you have a 220V product, turn off the power switch.
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 will be
away from you.
5 Lower the green lever with the flat green part fitting in between the
rollers. Press down on the green lever until a snap is heard.
