Rollers not picking up the paper or picking too many pieces at once.

Assumed you have cleaned out the feeding slot and sprockets that turn the feeder wheels. Often there's some piece of paper or gunk. One option that likely applies to most printers -- from another HP online source: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00190540&cc=us&dlc=en&lc=en

1. Look for paper that might have jammed inside the product. Use a flashlight to carefully view the areas around the rollers. Remove all traces of paper found.
2. Wipe the rubber paper-feed rollers with a lint-free cloth lightly moistened with distilled or bottled water. Rotate the rollers up carefully to clean all the way around.

1. Look for the paper pick roller farther inside the rear access area. The paper pick roller
   IMPORTANT : The paper pick roller is a bit more difficult to reach; however, it is the most important part to clean. Make sure to clean it thoroughly. If this roller is not clean, the issue will likely continue.
2. Clean the paper pick roller with a cotton swab moistened with distilled or bottled water. Apply a moderate amount of pressure to make sure that you remove all debris. Clean the roller thoroughly all the way around. Figure 8: Clean the paper pick roller

THE SPERATION PAD IS DIRTY OR WORN.TRY CLEANING THE SEP PAD WITH NAIL POLISH REMOVER.THE SEP PAD IS LOCATED UNDER THE ROLLER THAT PICKS UP THE PAPER

Hello,
Check to make sure that the rollers are not just sliding on the paper instead of gripping it. If this is the case, one thing you can try is to get some rubbing alcohol and cotton swab the rollers to make sure they are clean. Be sure to power down the copier first and unplug it.
Over time, the paper fibers build up on the rollers, and eventually, they get worn out. Cleaning them once in a while can prolong their lives and sometimes even revive "dead" rollers.
Also, let the alcohol dry before you try using the copier again.
Hope this helps!

The problem is generally associated with the pickup roller ( roller that rotates and pulls the paper from the tray ), and the separation pad, ( a stationary cork like material.) It sounds like you need to replace both.. The concept is like wetting your two fingers to separate pages, except in this case it is a cork base and roller that do the work..

You can alternately try to rough up the cork very lightly with sand paper, and clean the roller. The pick-up roller should have some slight ribbing, and if it is all gone, a new roller is necessary. As a temporary fix is just that..temporary.

This procedure is described relating to a different error, but it resets and clears everything and would be worth a try http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=110&prodSeriesId=66359&prodTypeId=18972&prodSeriesId=66359&objectID=bpl10206 hp says for your specific error: "Reload the paper in the paper input tray; verify that there are no jams in the paper path, and press MENU/ENTER to continue the job. If the error persists, replace the printer pickup roller. Check paper path, including rear output door for jams, fuser area, and under the print (toner) cartridge." here is the complete guide to all the above http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=110&prodSeriesId=66359&prodTypeId=18972&prodSeriesId=66359&objectID=bpl11283 ask again if you need more Hope this helps :)
