Faulty CIS (contact image sensor) or the flat cable connecting the CIS to the PCB. Error only appears when you scan/copy/fax. But printing function I guess is normal.

Try turning the printer completely off and then it back on after a few moments. Typically the start up cycle will loosen the paper. If this doesn't work, try also taking out your printer cartridge and pulling the paper slightly, if it's still stuck it won't give however sometimes it will let you pull it slowly from the gears. On this model I would remove all the paper trays and if there is a section on the back remove that as well. Try and find the spot that lets the paper give. Worse case take it to where you bought it, the technicians there may have see the same thing happen and may know where to remove it. I would suggest a store that offers technical service like best buy or staples, etc.
