Paper jam

wow..springs that are weakened...unfortunately, that's one key weakness in these sort of printers. When I do a repair, if the springs are shot(not unlike a car, eh?), it's time to replace em. Not much can be done to restore the tensile strength of something like that.
Got Backup?

Assuming that you are feeding the paper into the correct end of the printer :), it seems that the printer is defective, but
First unplug the printer from the wall, wait a few minutes,
and see if it resets. If that does not work, read on.
Also do not forget that printers are dirt cheap, less than the ink when it runs out, so this may not be worth your time and effort.
are controlled by "Stepping Motors"
Unlike an ordinary DC motor with two wires, that spins
clockwise or counter clockwise depending on the voltage
polarity,
a stepping motor contains several pairs of wires, that
are pulsed in a controlled sequence, causing the motor
to spin in precise angular steps. Depending on the
number of wire pairs (poles) and internal gears, the
stepping motor can have a resolution as course as
90 degrees, and as fine as 0.05 degrees per step,
depending on the cost and applications.
Linear stepping motors can even move an object in
a straight line.
The benefit of these stepping motors is that, unlike a
linear servo motor, they do not need complex positional
feed-back for precise control, they simply step as many
times as you tell them to. Four steps left, two steps back
.... etc.
ultimately controlled by a central processor within the printer.
Depending on the printer model, and how sophisticated
the printer's internal processor is, the paper and head
movements can be either automatically controlled by
SOFTWARE (firmware) within the printer itself, or by the device drivers installed in Windows.
The more self-sufficient the printer is, of course, the less
hassle and CPU overhead on your PC.
a) Skip steps
b) Get stuck
c) Oscillate back and forth
d) Spin backwards.
a) One bad wire in the ribbon connecting the motor
to its controller board.
b) Bad motor driver transistor: Open or shorted.
c) Bad data line from the printer's internal control
processor to the driver transistor array.
d) Bad processor chip, memory or firmware within
the printer, e.g. a burned out register or firmware
memory location.
e) Defective internal power supply, causing everything
else to malfunction.
f) Bad paper position sensor
d) Crashed control program, which is probably the
only thing that is fixable:
i) unplug the printer from the wall socket, wait a
few minutes, and see if it resets.
the Window drivers are corrupt but this is very unlikely.
Is one of the motor windings open or shorted ?
Is one of the driver transistors fried ?
This very much depends on your level of skill, and the test equipment you have to work with. If you don't have a decent oscilloscope you will not get far. Without a digital multimeter you will not get anywhere at all.
Call the manufacturer, scream blue murder, accuse them of setting your house on fire and giving your dog diarrhea ....
and see if they will send you a freebee.
Hope this explains it.

I had the same problem and found a small spring was loose and interfering with the paper. The Spring was on the right side as you look at the printer, near the bottom of the paper feeder. I took it out and it works fine, for now.

Just download the software from Epson's site. I don't think there's anyway to run the utility from the buttons, I'm afraid.

Is the message general error? The problem is tchip. When turn on chip is recognized by printer, but when start to print, printer "read" some information from the chip. Here is the error. Some pin at the chip for redaing the existence of chip, other pin for reading the information. Check connector between chip and carriage.
