Package includes: 1 x 9-Pin.  Regular (un-Winged).

• Replace broken CSIC pins on ECB (Epson Cartridge Board).  Epson's contact pins are notoriously easy to break.  When the pin break, it creases "cartridge cannot be recognized" error.  Instead of throwing the printer away, we can replace the broken pin with a new assebly.
• Package includes: One Regular un-Winged 9-pin assembly.
• If your 9-Pin looks weird and has two long arms on the top, you probably need this one instead (click).

How can I know what kind of CSIC my Epson uses?

• NUMBER OF PINS. Count number of pins on your broken one, if it is 9, then keep reading.  If it has 7 pins, then the product is not for you.  Go to here (click). 
• WINGED OR UNWINGED.
  • The winged pins are usually used by older models like Artisan 1400 1430, some Stylus and early models of WorkForce (e.g., WF-830, WF-835). They will have two long arms on the top.  Here is a picture example.  
    
  • The regular un-winged 9-pin is used in newer models such as WorkForce WF-3620 WF-3620 WF-7720 and Expression XP model such as XP-6100 XP-7100. It is the most popular 9-pin.
    
  • The regular (un-Winged) pins are more triangular.  The winged pins are rounder.
     
  • If your printer has a structure surrounds the 9-pin, so you cannot see if it has wing or not.  It should be regular (un-Winged). If you have a winged 9-pin, it should be very easy to tell.  Example of 9-Pin in Expression XP.  The top is covered by blue plastics but you can tell it is a regular from the triangular shape of the pins.
    WorkForce 6090.  You can tell it is a regular (un-winged) because 1) it is a WorkForce 2) It has triangular shaped pins.
