Document comes out crumpled

Paper is not feeding through your printer properly.

First thing you should do is to remove the paper from your paper tray. After removing, place the paper back in the tray, making sure it sits evenly within the tray. There should be no part of that is higher than any other.

Next, carefully close the paper tray, making sure that no part of the paper catches when closing. Do this by feel. If you feel any resistance when sliding the tray shut, pull the tray open and try again.

If this does not solve the problem, open the printer doors and take a look inside the printer. There might be something small impeding the paper's smooth movement through your printer.

Finally, take a few seconds to clean the paper pulls (the little rubber wheels you see inside your printer). If these are dirty, the paper will not be pulled through the printer in an even way. It could pull off track causing one of the sides of the paper to rub against the printer. This is what causes the crumpling. To clean the paper pulls, just use a damp cloth and gently wipe them. Good luck!
