Paper jam but no paper epson xp-400 mssage won't go out

SOURCE: Epson AcuLaser CX11N ADF Paper Jam

I had a very similar problem with the ADF, it resulted in ADF paper jam - message and then in Req Code 2011.
I checked sensors and everything else, then called a epson service professional.
After telling him the Req Code, he knew the problem and said that the problem is the board, which needs to be exchanged, mentioning that this spare part is expensive.
I then checked the whole ADF again, now opening the long grey cover on the backside, I disonnected the connector cable from both sides and - using a multimeter - checked this connector cable for breaks.
Result: the violet cable was broken, so I soldered in a new wire, using the last cm of (old) wire on each side - and now the ADF works fine.
This cable is easy to change if you get the spare part, there is a connector plug on each side, on the ADF side is an additional ground wire (green) fixed with a single screw. Thats it !

For the electronic experts: the configuration of the connector:
sourrounding metal cover = ground, thick green Wire on the ADF side
If you turn the plug that way, that the two single contacts are on top, these are the colours:
1st row: brown - black
2nd row: green - yellow - orange - red
3rd row: grey - violet - blue

Hope this helps

I'll need a little clarification to diagnose this but my guess is that you have something blocking the path of the printhead.

There are two possible diagnoses...
1. Service error: This is when the waste ink pads are full.. It's indicated by both ink and paper lights alternating with each other. I doubt very much this is the problem...

2. General or "Fatal" error: This is when something stops the printhead from doing its job and usually follows something like a paper jam where something has been left behind or been pulled out of alignment when clearing the jam. I'm betting on this being the case.

Here's a few things to try.

• Check to see if the printhead can move the full width of the printer. Note any areas it has problems reaching like the parking pad.
  
  
• If you can identify an area that it's stopping at, note the direction of travel and see if there's anything in the way or out of place in that direction.
  - A common one is a bit of paper that's become covered in ink making it hard to see, sticking up and blocking the path.
  - Another is the parking pad or cleaning station being pulled out of position.
  
  
• Check that all the rollers and paper guides are uniform and there's no obvious lifting. Sometimes they can be pulled out of alignment and just need nudge (carefully!) back into position.

Couldn't fix the problem, but the Epson people have agreed to send us a new unit when the tech supprt people couldn't provide a solution. We are to send the old one back. I'm glad this happened while the printer was still under warranty. Hope this doesn't happen to someone else, but we're pleased with Epson's reponse.

SOURCE: Epson Stylus 580rx won't identify vellum paper

Ran into the same problem. The problem is that the printer's paper sensor sees through the vellum and therefore doesn't think any paper moved into the print position. To use vellum, fold up 1/4" edge on a standard peice of print paper and place the leading edge of the vellum under the flap. Place the paper and vellum into the printer and print. The printer will pull in the paper and the vellum together. Make the paper fold tight and straight to prevent jamming. You will need to feed one sheet at a time. Also the Epson inks take a long time to dry on vellum. I let mine dry overnight.

SOURCE: Epson Stylus Photo R350 giving a paper jam error message

An Epson service man (he was VERY kind to suggest this) told me to use a weak detergent solution on the rollers, NOT alcohol as that will dry out the material the rollers are made of. Although the problem has recurred a couple of times, it's worth repeating when necessary. I actually activate the 'print' command so it tries to feed in paper, while I FIRMLY hold a piece of fine cotton cloth stretched over a thin plastic ruler, which I hold down where the paper feed grabs its paper. The printer has a couple of tries to feed paper, reports an error message (because there was no paper) and I activate it again, thus exposing the WHOLE of the feed wheel to the cleansing cloth! WORTH A TRY!
