Turn the rollers with your fingers

Try putting Isopropyl alcohol on the feed rollers. These rollers become hard and smooth with time and cause all sorts of paper feed problems. You can find isopropyl alcohol at any drug store(it is rubbing alcohol).

It is probably stuck permanently, and the fuser will need to be replaced. I believe the "fuser replacement" instructions are in the manual.

Try removing the Toner/drum unit and see if paper is there. Also check the rear access door to see if paper is stuck in the fuser.
Sometimes you will get a jam where the paper has not even left the paper tray. Try removing the paper tray and cleaning the paper feed roller with and cloth dampened with a little water. The roller is located just above the center of the tray.

It could be several items causing that. Lets go simplest to most difficult.Remove the paper tray completely, What you do is pull it like you were going to add paper, but give it a slight lift upward and it will come out. Look in there and you will see the feed tires they are "D"shaped and they should have some texture to the surfice. Take some alcohol and clean them a few times to remove all contamination. But if they are smoothe, they should be replaced. You have to run a lot of copies on them to wear them out though. Also try spinning them a couple of times to be sure the latches that stop them from multifeeding are not just stuck.
You know what, lets do this the right way. After you take the paper tray out. also take your toner cartridge out, then lift the machine and lay it on its back so you can see the peper feeder totally. But make sure you remove the toner before you lay it on its back. You may also want to remove the document feeder prior to laying it on its back. That way you can see the rollers batter, look into where the paper feeds and see if there is anything blocking the paper path. Who knows a small pirce of paper may be stuck in there, or a staple or paper clip.
Then check the paper tray carefully, press the plate down and see if it springs back up.
Once cleaned and inspected, replace the tray and toner and try and run the machine. If if still jams, you want to move the machine out fron the wall and remove the back cover. There are 6 screws holding it on. You will want to look near the bottom of the frame, there is a whits grar, cam type drive . It is white, about 2 inches in diameter and about a half an inch thick. There is a solonoid that engages to release the peper feed, run the machine and see if that assembly is realsed to feed paper. If not, the solonoid or the main board may be bad.
There are metal fingeres in the paper tray also that press right on the corners of the paper to stop multi sheet feeds, they may be slightly bent also. They are on either side of the peper when it is in the up position. You can try seeing if the move freely up and down when the tray is out.
Also when you have the machine on its side, look at the clear mylar strips in the paper feed to see if one of them are tucked under.
I suspect dirty or worn rolls, or something to do with the paper tray. That is mostly where mis feeds occur.
Please let me know and we will look more into it.

The rollers need to be clean or replaced.
