Error says paper jam, but there is not. What could cause this?

So for me the idea of removing all the ink cartridges and reinstalling them one at a time and moving the carriage over to the far left worked. All is working now. Thanks Andrew

Epson xp300 paper jam every time even with no paper. i took it apart and found out exactly what is going on with these printers. i also took pictures of the area that needs attention. it's a simple fix and it's due to epson's poor design. they have not allowed enough material to hold the paper jam detector in the correct position. The sensor works off of a small black or brown piece of plastic that runs across the back of the roller assembly that catches the edge of the paper to get it started into the carriage area. One end goes to the main circuit board and controls a hall effect switch, the other end goes to the middle of the paper feed area and has a thin arm that sticks in between the rollers and it swings when paper is fed past it. When it swings the hall effect switch is open. meaning the switch is not detecting the normal blocked state by the arm. the arm will swing to open the area that is normally closed and will block the path of the switch.

So the cause of the jam is due directly to the tabs that epson has in place to hold that black or brown arm in position. The tabs will eventually sag downward and will either bind up the arm so it cannot fully swing closed again or it will move the thin part so it hangs up on the rollers and will not allow the arm to fuller return to the position it needs to be to close the gap in the Hall effect switch. First thing I did to confirm this was to push on the arm where the hall effect switch is on the board and it stopped the paper jam instantly. So there is a need to examine exactly why the arm is not fully closing.

Mine had to be adjusted on both tabs and also needed to be adjusted in and up, meaning i had to bend both tabs upward to get the piece that blocks the hall effect switch back into a fully closed position which it did look as though it was doing until i looked closely at the position and saw it was a tiny bit lower than it could be. then I saw it was also hanging up on the other end between the rollers. So that needed to be re-centered between the rollers. to do this you will have to bend the tabs left or right (both tabs will probably need to be bent to position it in place and not allow it to have any free play.

I used a very thing flat screwdriver and a magnifying glass with a bright light. The position is actually not that critical it just needs to be positioned correctly so it blocks the hall effect and is not hanging up. It will take about 5 minutes to fix, I removed 4 screws 1 on the center of the back piece near the bottom, another from the top left of the scanner (while facing the back of the printer) where the hinge is located there is a screw running into the hinge. then carefully remove the scanner and unplug the ribbon cable on the right side.

You will need to remove the back plastic cover piece that is under the scanner and that screw is on the left side near the hinge area just behind the hinge. the screw will be running horizontally and will have the head facing left. there is also another screw that holds the white hing in place it's just at the base of the hinge down inside the printer body a n inch or so. Then remove the cover piece by pushing it to the right and up, you may need to pry it slightly on the right edge to get it started. twist it upwards while pushing. this will expose the main board and the black arm very easily seen and very easy to access to correct the position. test it with the cover or the scanner back in place before you go any further. if the jam is cleared unplug it again and reassemble the cover and the scanner don't forget to plug the ribbon cable in before the cover goes back on.

It's just that simple. i think it happens over time from normal use since epson has made the tabs so weak and they probably only set that arm to barely clear the rollers it won't take much to create a problem. i would go as far to say that they do this on purpose just to make extra money. it could easily be avoided with a tiny bit more metal allowed on the tab or just a simple extra bend on the edge to add a tiny bit of rigidity to stiffen the tab and hold the the position better. This would not even cost epson anything to stop the problem, I'm sure they know exactly what's causing it and are happy it has made them millions. You will never get any real answers from their tech support and they will make even more from you calling, they will never admit they know nor will they ever tell anyone to even consider looking at that area. They will lie to every single person who calls and try to get them to buy another printer and trade theirs in, so they can bend the tabs in 5 minutes and resell it again.

Had the problem with a SX440W and after some hours trial and error and chatting with the support, who told me to send it in for 95 Bucks, I finally found the error.

I had a real paper jam and pulled the paper out backwards. At the bottom of the top paper feed there is a black plastic stick, which is the paper jam sensor. When pulling out the paper, the stick did not switch back. I opened the printer top (2 screws) and put the stick back where it belonged. After that it prints like new!

Johnny Long here from Hendersonville NC. Have a WF-3540... same problem. Tried all the solutions posted here - no cigar. FOUND THE SOLUTION - will work for this model and most others, I suspect. I opened the back of the printer (remove rear cover) and noticed in the center of the paper path, there is a 3/16" wide plastic tab. That senses whether there is paper in the path. You need to GENTLY insert a letter opener - or the flat blade of a dinner knife and cycle that tab up and down. VOILA'! Your printer will reset and remove the paper jam message. See my photo for the tab in the CENTER of the paper patch. Now, ENJOY YOUR PRINTER! - Johnny

Epson WF-2540: paper jam, squealing noise on power up.

I tried cycling the printer off/on; gently inverting the printer; cleaning the printer rail (there wasn't any sign of residue); blowing compressed air around; removing the ink cartridges; all to no avail.

HOWEVER, I noticed that the approx 10" x 1-1/2" clear plastic paper dust-cover thingy that normally has integrated pivot pins on either end, was missing one of the pins - someone (I have 4 kids) had broken it.

I removed the paper and peered down the slot with a flashlight, and lo and behold, I thought I saw a tiny piece of plastic wedged in the paper intake rollers. My son held the printer upside down while I poked up into the paper slot with a long skinny knife to dislodge what turned out to indeed be the broken off plastic pin.

The printer works fine now :-D

If your Epson printer is displaying a paper jam error18773227003, follow these steps to resolve it:

Turn off the printer and unplug it. Open the rear and front covers to check for jammed paper. Gently remove any stuck paper, ensuring no torn pieces are left inside.

Use a flashlight to inspect the paper feed rollers. Clean them with a lint-free cloth and a few drops of water to remove dust or debris.

Use clean, dry, and correctly aligned paper. Do not overfill the tray.

After clearing the jam, restart the printer and try printing again.

If the error persists, check for sensor blockages or update the printer firmware via Epson’s official website.

08.09.2015: Espon WP-450 - Phantom Paper Jam

This might be a bit different but today I had issue with phantom paper jam, only when I printed from Firefox. All files that were on the PC printed fine. So figured there had to be something up some where other than the printer..

So....I had loaded HTC phone software to my computer. This is the only think different from the day prior.

So I deleted the software and the drives through uninstall, but it did not remove the HTC file under C:\Program Files (x86) HTC (file has 6 folders in it) - so, I went to manually delte the HTC folder and could not do so. It still had something running, not could not be deleted.

So, went in and deleted one by one, till I was left with the file that was running: Internet Pass Through Service exe.

Went to task manager to shut down and denied access thinking if I shut it there I could delete it.

So approached it through Services (tab in lower right corner of task manager)

Services opens up, scroll down until you find the Internet Pass Through Service (name might not contain all words, but you will see it)

Right click on it and stop it.

Then go back and delete the file.

Problem solved, printer now works fine.

Hope that helps anyone else with this type of issue.

I hope this works, but it may be a different situation. Your printer might have something stuck between the conveyor, for example a pencil like me. All you need to do is to remove the pencil. You might need to take your printer apart though.

Hello all,

I had the same issue after a 'paper jam', I'm using Epson Stylus NX100. After MANY issues leading up getting my printer to print again, once it started working and tried to print for the first time in a year I got this crap.

PLEASE TURN OFF YOUR PRINTER, UNPLUG THE POWER AND THEN PRESS THE POWER BUTTON AGAIN FOR GOOD MEASURE!

My solution, was to create another jam since I pulled the paper out from the top (going the opposite direction as the paper should have been going). I had to remove the scanner (A couple ribbon cables), it snaps right back on, there's a little door you can push out to access to reconnect them. Then comes the outer shell part, which is much more simple (3 screws on the back), there is also a ribbon cable that happens to be the power cable so don't forget to put it back!

Once you get the paper to the end of the tiny black rollers attached to the white plastic pieces there is a gear on the left side that has some sort of clear plastic piece on it. Gently roll that so it feeds the paper further down. Let go about half way down. Put everything back together and you should be good to go!

I also had non eom ink cartridge issues, and lots of "empty ink" following up to this. I was able to fix that and would gladly explain to anyone who may be having the same problem.

I hope everyone has got this problem fixed or at least this helps!

I have an Epson SX435W that came up with a warning on the printer screen. W02 warning paper jam. There was no paper jammed, no miss feeds the paper feed path through the machine was clear. I solved the problem by going to the maintenance menu and selecting change cartridges. select this option, lift the scanner lid to show the cartridges, the machine will then take the cartridges to the area on the right of the machine where you can remove them. Remove the cartridges and put them to one side. Turn off the power, remove the mains plug. then leave the machine lid open and let it remain unpowered for AT LEAST one hour. During this time I flushed the printer heads through using a kit called Pristine Cleaning Fluid from Amazon at £6.99. I actually let it stand for over an hour. After head flushing make sure you push the cartridge carrier back to exactly the same position on the right hand side of the machine. Of course you can skip this step altogether. Plug the machine back into the mains, switch on then the menu will tell you to install the new cartridges go through installation procedure in the normal way and hey presto my machine was back as before no paper jam warning and I printed off thirty pages just to be sure. One final point after installing the cartridges the menu will show charging the system. Lots of whirring and buzzing it seemed to take quite a while so be patient. Good Luck Allan Q

My epson wp610 had a phantom paper jam - ck'd every answer after I installed a new CIS ink system and could not find a solution that worked.

Finally, someone gave me a clue in these answers, took out cis, pushed air thru each ink nozzle in unit, then reinstalled cis.

Worked first time. Something must have been blocking nozzle, I never found any debris.

Hopes this helps some one.

Do you have a wifi router connected to your printer??? If so, the router could be corrupted. Mine was hooked up to my desktop and wifi router. For the past week, the LCD screen on my printer kept showing a paper jam, but there was no paper jam. I talked to my Internet service provider and explained the problem. She told me it could be the wifi router that's messing up my connections. I took the router off the modem, printer, and desktop and my printer is functioning again. If that's your problem, it's way more cheaper to replace your wifi router than going out and buying a new printer...

I had a grinding noise repeatedly jaming feeder. The problem was that the three gears on the side of the duplexer (see epsons website for what part that is) were no longer aligned with each other so that the paper could only be fed up part way. I pushed the third gear back into engage the other two and the problem was solved.

Sometimes, it happens that the Epson printer shows paper jam and it won’t print but there is no paper jam in real. If you are sure there is no piece of paper somewhere inside the printer, then try out these methods to fix paper jam. Reset the printer, which might clear a false paper jam error, and then try to print again. With the printer turned on, disconnect the power cord from the printer.

1. Unplug the power cord from the power source.
2. Wait 60 seconds.
3. Reconnect the power cord to a wall outlet and to the printer

I have a wf7720 that has been down for about 6 months or better. I took the Ink out, moved cartridge back and forth and did a print head cleaning and it worked. Thanks so much

There are two possible workarounds:

1. Use usb printer cable
2. In the Epson printer settings, tick the setting "use bipolar connection" OFF.
