How to fix Epson printer not recognize refillable or CIS cartridges

Follow

 

Contact points

  • Make sure the cartridge chip is clean, free of ink smear and debris.
  • Make sure the printer's contact pin is clean, free of ink smear and debris
  • Verify that the cartridge is seated in the printer securely.  Push it down hard until you hear a click.  Once it is inside, wiggle it with your finger back and forth.  If the cartridge seems to be loose, insert folded paper to the back and thus push the cartridge forward to have good contact with the printer.

Installation

Possible Causes:

  • If you installed cartridge with power off, then printer won't know you changed the cartridge.  It will confuse the printer and thus cause cartridge error.  
  • Sometimes Epson printer won't erase previous error code.  When it has a depleted OEM cartridge error, and a non-OEM cartridge warning come together, it causes the printer to display "cartridge not recognized".

Things to try:

    Nothing worked. New cartridges. Power off direction, failed. Cleaned ports failed. Contacts not touched, not greasy, wiped down ports with alcohol swab.
    These are guaranteed replacements but, the Epson replacements I had replaced had the same issue with recognizing as well. Computer expert happened to be visiting and worked her magic on it BUT she is no where in the area any longer. In the life of this printer I have spent more time with maintenance code issues than actually printing. There is a plan with all printers and technology for that matter to always make any software, parts, even electrical supply cords exclusive to their products only to make you pay ridiculous prices and stay locked and dependent on them. Happened with my Brother, Lexmark, Kodak and now my Epson. Expensive printer only made about 50 prints on it 100 max.

    MIssy this can be the firmware causing the issue recently epson has been doing updates to stop from using third party ink there are some work arounds but not all might work you may want to disable auto updates hope this helps

    Auto update disabled my WF-4740. Will no longer recognize my third party cartridges. Any workarounds? Have already tried downgrading firmware to an older version but the upgrade must have set something else in the printer that isn't effected by the down grade as it won't recognize my cartridges. Had a epson yellow cartridge that still had ink so I put it in and it was recognized.
