Epson 2200 ink replacement light stays on

I had the same problem with the light black and light magenta as well. It took trying only one new cartridge with the light magenta before it worked.
The light black took 4 new cartridges before it worked. I had called the Epson support center on this problem and after going through suggestions they made that did not work, I told the guy I had another new cartridge on hand. He said to go ahead and try it. This time the printer worked. He took my name and address and said the other cartridges were faulty. Epson is sending me new replacement cartridges at no charge.

This means that your printer wast pad is full this now you reset your printer but make sure you have put new pads in 1st

1. Turn off the printer power and unplug the power cord from the wall. Disconnect the computer interface cable at the back of the printer.
2. After one minute reattach the power plug to the wall, but don’t reattach the computer cable.
3. Hold down the ROLL and the PAPER ADVANCE buttons simultaneously.
4. Turn the printer on. after 2 blinks, all the ink lights come on, then release the buttons being held down.
5. Press and hold the ROLL button for 10 seconds.
6. Release the ROLL button and the printer will initialize, which resets the Waste Ink Pad Counter.
7. Once initialization is complete, turn the printer power off.
