I replaced an ink cartridge and my product shows that the same ink cartridge is expended. What should I do?

• If you have just installed a new cartridge and you still see an ink related error, the cartridge may not be installed correctly.
  
  Follow the steps below to make sure the cartridge is correctly installed.
  
  Note:
  We recommend that you use genuine Epson cartridges and do not refill them. The use of other products may affect your print quality and could result in printer damage.
  1. Make sure the printer is turned on.
  2. If you see a message on the printer's LCD screen to install or replace an ink cartridge, press OK.
  3. Open the scanner unit.
     
     Note:
     Do not move the print head by hand; otherwise, you may damage your product. Do not touch the flat white cable inside the printer.
  4. Press down each ink cartridge until it clicks into place. (If a cartridge is properly seated already, you may not hear a click.)
     
     Note:
     When you installed the new cartridge, you should have removed the yellow tape from the bottom. If you know you removed it, skip to step 5. If you're not sure, you can pull out the cartridge to check. (Squeeze the tab on the cartridge and lift it straight up.) Remove the tape if necessary, then reinstall the cartridge, pressing it down firmly.
     
     
     Caution:
     Do not remove any other labels or seals, or ink will leak.
     
     Warning:
     If ink gets on your skin, wash it thoroughly with soap and water. If ink gets into your eyes, flush them immediately with water. If ink gets into your mouth, spit it out and see a doctor right away. Keep ink cartridges out of the reach of children.
  5. Close the scanner unit.
     
  Caution: Never turn off your Epson printer while ink is charging or you'll waste ink.
