Replace the feed-roller assembly

Occasionally, if streaks on scans or paper jams occur repeatedly, you might have to replace the feed-roller assembly. To order the replacement part, go to www.hp.com/buy/ parts. Instructions are included with the replacement part.

Note HP recommends that you replace the feed-roller assembly every 100,000 scans. Use the HP Button Settings Utility to keep track of the scan count. For more information, see the General info tab in the Button Settings Utility.
