Jammed
First of all, look at the paper you pulled out - if it's in one piece, no corners missing, then the error isn't a paper jam thing.
Now turn off the printer, push "stop", maintenace button and power button toghether, till a message appears.
I also found the following tip that's also related to the same error, could be usefull:
"As Epson printer users will know, waste ink from head cleaning etc. is channeled into absorbent pads in the base of the printer.
Eventually these will fill up and need to be replaced, and some time before they actually fill the waste ink counter in the printer's firmware will signal an error and the machine won't print any more until the counter is reset.
This normally requires a trip to the service depot (if the printer's worth the cost, and if it's realised that this is the problem -- lots of otherwise good printers go to the dump through this relatively minor problem.)
The service depots have a program that can, among other things, reset this counter (but of course won't part with it -- there's money to be made, new pads to be sold...)
There's a third-party utility available that can do this (look for sscserve.exe on the 'net -- carefully read the documentation and use it with great care...), but at the same time the pads need to be changed, otherwise you risk ink pooling in the base, sometimes finding its way out and making a right mess.
Replacing the pads isn't for the faint-hearted, you have to virtually dismantle the printer to reach them.
Here's how to get around it -- the two pictures below are almost self-explanatory:
On the left rear of these printers is a small trapdoor held by a single screw.
Remove it, look inside (down and to your left) and you'll see the waste ink tube.
The tube is free at one end, and with a suitably curved piece of wire you can hook it and wangle the end out through the opening (you may dislodge a small piece of plastic in the process -- just put it back where it was, it's only a vibration damper.)
At this point, you're almost there.
All you need now is a suitable container for the waste ink, and to file a small slot in the trapdoor cover so you can put it back without pinching the tube (or you could just lave it off.)
The container in the photo is a small square one with a snap-on lid, approx. 60mm square and holding about 150ml -- they're sold in sets of three for a few cents and are for making ice-blocks etc. in your freezer.
Make a hole in the lid as shown (slightly larger than the tube to let air escape) insert the tube and forget about the internal pads forever.
(I've used a new machine for the photos, don't expect the tube in yours to look so clean.)"
Good luck
