• 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.

Content paper jams with my L7590

Here is a link to HP's support docs on the subject. (and here) and here and here.
If you have access to compressed air you can GENTLY blow through the machine to remove dust that's built up.
Otherwise, here is the home page for support for your printer. Perhaps there's some info in the hp forums that may help....
Best of luck!

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Open the adf and rotate the pick assembly till you hear a click and then take a coin and run it up and down against the separator pad and then see if the adf picks the paper or not.If this does not work try this *# 329 and scroll thru and select adf pick test if that fails its time for you to get the printer replaced or get an upgraded printer

3 possibilities.
1 If you use this macine to copy labels, there may well be a small piece of a label stuck in the paper path on the crumpled side. Or a small bit of paper.
2, the paper pickup on the crumpled side is 'polished', and no longer feeding the paper at the same time as the uncrumpled side. They can be cleaned with rubbing alcohol. Though that is a temporary fix and the paper pickups should be replaced if cleaning fixes the issue.
3 The fuser film has a tear in it on the crumpled side you need to rule out 1 & 2 before going to three again replaceable but a bit more difficult
