EPSON UNRECOGNIZED CARTRIDGE ERROR
Regarding your recent inquiry about the Epson T126 cartridge error me ssage (“Cartridge Not
Recognized", "Replace Cartridge", "Installed ink cartridge is expended." or similar cartridge/printer alert
message) associated with your Epson NX430 printer, the cartridge probably has a mis-programmed
smart chip during the refill process. Refill operators utilize smart chip re-programming equipment; in
rare cases during the re-programming which typically yields a green light to show success, it does not
always result in correct smart chip reprogramming. In this case, they may have forgot to re-program the
entire set of tanks. Unfortunately there is nothing you can do from home....the chip(s) need to be re-
programmed at the store. We suggest you return to the store and request the operators to re-program
and check the weight of all cartridges.
OTHER POSSIBLE CAUSES OF FAILURE:
1) Either the external chip or internal ink sensor is electrically bad (the internal ink sensor detects if
cartridge is really out of ink). If you return the cartridge to your retail refiller and they re -program the
cartridge(s) a 2
nd
time but the “replace cartridge” message, or similar blocking message persists, then
this is the likely cause and the cartridge will need to be replaced with a new one.
2) Ink cartridge may not be filled properly – your refiller would need to weigh cartridge to verify. If the
ink sensor does not see ink in the printer it does not matter how many times you reset the tank.
3) The chip resetter (at refill store) has an issue – if we suspect this is an issue we would contact the
store directly. Please disregard for now.
Now, you indicated that you attempted some troubleshooting steps.
Please quickly double-check a few additional items from the checklist below before returning to store:
1) Confirm if this is just a nuisance/annoyance alert (i.e. “non-genuine” cartridge ) vs. an actual
'unrecognized cartridge' alert (i.e. Red X's on printer display / Windows pop-up message). Please visit
the following Inkjet411 support page which will help you delineate the difference:

2) On some Epson printer models you may need to scroll thru the menu options AT THE PRINTER'S
CONTROL MENU (i.e. right arrow key) to help determine which specific ink cartridge is actually causing
the ‘Unrecognized Cartridge’ error condition. On the other hand, for general 'non-genuine' cartridge
