• If the automatic document feeder (ADF) does not pick up any pages at all, the rollers inside the automatic document feeder need to be cleaned.
• If the automatic document feeder picks up multiple pages instead of single sheets, the separator pad inside the automatic document feeder needs to be cleaned.

SolutionLoad one or two sheets of unused plain white full-size paper into the document feeder tray, and then press Start Copy Black to pull the pages through the automatic document feeder. The plain paper releases and absorbs residue from the rollers and separator pad.NOTE:If the automatic document feeder does not pick up the plain paper, try cleaning the front roller. Wipe the roller with a soft lint-free cloth dampened with distilled water. If the problem persists, or the automatic document feeder does not pick up the plain paper, clean the rollers and separator pad manually. Follow the procedures below to remove the face plate from the front of the automatic document feeder, access the pick assembly inside the automatic document feeder, clean the rollers or separator pad, and then reattach the face plate.

Hi
Check the following
--Check the paper in the ADF (automatic document feeder)
--Make sure the ADF pick assembly is in good working condition
--Remove the document feeder and open the ADF cover.
--While lifting the blue-green lever, carefully rotate the pick assembly toward the open ADF cover until it stops.
--Make sure the bottom roller is held firmly in place by the two-catch, which is located to the left and the right of the roller.
--Clean the rollers and separator pad

This link will take you to your users guide on the HP web site. Go to "Maintain and troubleshoot">"Clean the device">" Clean the automatic document feeder (ADF)".

It only takes a small piece of paper left behind, 1/4" square or less, to keep document feeder from working properly. GOOD LUCK!

hello!

have you tried cleaning the separator pad inside the automatic document feeder?

try to Load one or two sheets of unused plain white full-size paper into the document feeder tray, and then press Start Copy Black to pull the pages through the automatic document feeder. The plain paper releases and absorbs residue from the rollers and separator pad.

If the problem persists, clean the rollers and separator pad manually
