Pen fell into paper feed mechanism..

Jam E normally cause by the paper path sensor came off during when you clear a paper jam.. the sensor is located at middle side , to fix it back you will need to remove the E cover..and remove the transport unit...4 screws.. but putting it back will need to have some technical know how as fitting it back wrongly will cause you unit not able to feed paper due to the plastic blocking the paper path.
Will upload some instruction later...

The pen has fallen into the blower housing and is hitting the fan blades.

Unplug the dryer!! Remove the two screws at the top of the lint trap. Remove the rear panel. Remove the four screws at the bottom that attach the lint filter housing to the blower housing. Then, remove the pen from the blower housing.

Every time I see that it's just something that fell into the back slot. Sometimes screws, candy wrappers, pens, push pins. That printer just doesn't do that without something falling in. One person shook it upside down and a BIC pen fell out. Check inside the back before you pay expensive repairs. I charge $69.00 to remove whatever is in there.

Usually it's because something has fallen down the back where the paper goes. One person on here turned her printer upside down and shook it and a Bic pen fell out. I got one last week with a wood screw inside. sometimes I find push pins, candy or jewelry. If nothing comes out try looking inside with a light and small mirror.

Every time I see these I find pens, candy, clips, other objects have fallen down the back where the paper goes. One lady picked up her printer, turned it upside down and shook it and a bic pen fell out, It worked fine after that.

Use a flashlight and small mirror to look down where the paper goes in the back, usually something has fallen in where it shouldn't be. A lady last week turned her printer upside down and shook until a bic pen fell out.I find pins, paper clips, toys, or gum inside. That one roller us usually enough.

you must have objects foriegn objects inside your printer. i.e. paper clip or some other object . Get your printer and move it side to side see if you can here anything moving about. once its out then perform alignment of rollers using epson maintenance menu.

1. Remove Shredder from paper catcher bin
2. Remove shredder cover from shredding mechanism assemble (approx. 6 screws on bottom of cover)
3. Separate shredding mechanism from bottom cover (may have disconnect circuit board from assembly and other wiring from switches , sensors, etc,)
4. Remove motor gear cover (approx. 4 screws)
5. Separate shedder main drive gear from motor step up gear by pulling gear out
6. Turn shredder mechanism up side down to access the cutting blades
7. Use an adjustable wrench to turn the main drive gear to see stuck paper
8. Use a needle noise pliers to remove paper shreds
9. Repeat step 7 and 8 until all shreds are remove and cutting mechanism move smoothly
10. Reassembly before testing shredder
11. If you remove only some of the shreds, the motor may seize up and strip the plastic gears from step up gear.

I have just removed the panel where the power and USB cable lock into. It's a case of 1 screww from the rear and 2 catchs underneath the printer. From there you should be able to see the mechanism for the roller, a set of small white cogs. below that you should be able to see a very small spring which is acting as the pressure. Mine was still attached but as you say was pulling no pressure on the roller what so ever.

Solution:
Find yourself a large-ish rubber band and slip the band over the whole mechansim. Best way is through the paper feed slot, slip it over the roller and then move it through to the area where you removed the panel. Position the rubber band as far down the cogs as possible, don't worry the cog casing prevents the band interfearing with the cogs. Now pull the band reasonably tight and with the other hand test the pressure of the roller. Adjust till you feel OK with it. Now put the panel back in with the end of the rubber band trapped and poking out from the panel behind the printer, holding it in place. Redo the screw and give it a try.

My first attempt found it a bit too restrictive and feeded to sheets at a time but adjusted it once and its back to normal. I know its a bodge but its a cheap one and it uses a rubber band, just how I fixed my Punto's windscreen wiper, £120 part or a rubber band once a month... Mmmm...

My husband took the top cover off the printer and took a good look inside with a flashlight. He found a hot pink crayon stuck where the paper feeds through. I guess I should have had a better look initially, since the paper never made it all the way through the printer. Works like a charm now!!
