   Note Make sure you pull out the paper support until it clicks.
   
   

If there is paper trapped physically then it must be removed mechanically by removing the roller assembly and resetting. You need to check forr pieces of paper that have jammed or is obstructing the sensor as it displays the error.
Now if there is no paper locked within it can be failure of the optocoupler sensors that is causing the error. There are placed at the take up paper in-detect section and can be confirmed using a test for continuous voltage feed from the sensor.

Open the front of the printer and remove (pull out) the fuser, check for and remove any stuck paper. Re-insert the fuser and close the printer.

Sorry to hear you are having problems. Printers can be very frustrating at times. Below is a description of how to completely clear paper jams. Paper can get jammed in there pretty tightly and in very small places. Ensure you've followed all the steps to clear your paper jam and you should see your printer start working again. Refer to your user guide (or download via the link provided at the bottom) for illustrations.

1. Open the front of the printer.
   
2. Slowly take out the drum unit and toner cartridge assembly. Some of the jammed paper will be pulled out with the drum unit and toner cartridge assembly.
3. Set the drum unit and toner cartridge assembly on a piece of disposable paper or cloth in case you accidentally spill or scatter toner.
4. To prevent damage to the printer caused by static electricity, DO NOT touch the electrodes inside the printer.
5. Close the front cover.
   
   Note: Do not put the drum unit and toner cartridge assembly back in at this point.
   
   
6. Pull the paper tray completely out of the printer.
7. Pull the jammed paper down and out of the printer.
8. Open the back cover (back output tray).
9. Still looking at the back of the printer, pull the tab toward you to open the fuser cover.
10. Pull the jammed paper out of the fuser unit.
    
    HOT SURFACE
    After you have just used the printer, some internal parts of the printer will be extremely hot. Wait for the printer to cool down before you touch the internal parts of the printer.
    
    
11. Close the back cover (back output tray).
12. On the drum unit you set aside, push down the green lock lever and take the toner cartridge out of the drum unit. Clear the jammed paper if there is any inside the drum unit.
    
    
    CAUTION
    Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
    
    To avoid print quality problems, DO NOT touch the roller part of the toner. Try to keep you hands, fingers and everything else away from there.
    
    
13. Put the toner cartridge back into the drum unit until you hear it lock into place. If you put the cartridge in properly, the green lock lever will lift automatically.
14. Open the front cover. Put the drum unit and toner cartridge assembly back in the printer.
15. Put the paper tray firmly back in the printer.
16. Close the front cover.
17. Make sure that the Error LED is now off.

If you receive an "Open front cover" error message the solution is to open the cover and remove the paper and any remnants of the paper jam. If there is no obvious paper remnants jamming the printer and you continue to receive an error message I would suggest unplugging the printer from the power source.

After 5 - 10 minutes plug in to power source.

Turn on printer.

See if this has resolved error message. If not you will need to check more carefully for paper remnants that would be causing the printer to detect a jam.

Trust this is helpful. :)
