Today’s topic is based on the non- recognition of ink cartridge in the Epson printer. So, here we will look at why this happens. And also a quick fix in order to resolve the issue of ink cartridge not recognized on the Epson printer.
Reasons Why Ink Cartridge not Recognized:

Internal Memory Reset Needed:
Your printer should automatically recognize when you install a new cartridge and reset its internal memory. Ensuring that it’s displaying full ink and toner levels, etc. However, sometimes the printer just doesn’t do that correctly and believes that the old one, or no cartridge, currently inserted instead.
Protective Strips haven’t been Removed:
If you haven’t removed protective covers or plastic strips attached to a new cartridge. When you first take it out of its packaging. The printer will fail to register the new cartridge and this will cause problems. Take the cartridge out of your printer and make sure all strips. Tabs or plastic covers removed before installing the cartridge again.

Dirty/damaged contacts stop chip data being read:
The new ink or toner cartridge has a number of metal contacts that connect to similar metal contacts in the printer allowing them to communicate. Dirt or damage on the contacts inside the printer can prevent the contacts from connecting and can stop the printer from reading the information on the chip.
HP Cartridge Protection Enabled
Whilst updating the firmware is often necessary. If you have an HP printer an update may be installed to ‘enable cartridge protection’. This prevents these cartridges to form working in any other printer. Cartridge protection may also stop compatibles from working in your machine at all. This can be switched off.
The Incorrect Consumable Installed in a slot:
A rare occasion but this does happen! It’s quite an easy mistake to put a color ink or toner cartridge into the incorrect slot or purchase the wrong cartridge model for your printer. Also, if a drum or fuser or another maintenance item accidentally purchased instead of a toner cartridge and installed without the toner, the printer will not work and still needs a new cartridge.
Take all the cartridges back out of the printer and double-check they were in the correct color slots and all the required cartridges are present. If not, reinstall them and switch the printer off and back on to reset the system.
An Ink cartridge has not been inserted in its slot correctly:
There is also the off chance that an ink cartridge wasn’t fully clicked into its designated slot. So the printer can’t detect the new ink cartridge and displays the error message. All you’ll need to do is lift your cartridge cover again and double-check each of the inserted cartridges to make sure that they have been clicked in, then close the cover again and try once more.
In the case of toners, sometimes broken plastic parts can cause the toner to not sit correctly into the printer slot. You would need to replace the toner to fix this issue.
A printer software update has rendered the chip data useless or stamped it with an ’empty’ status

This is one of the main causes of compatible ink or toner to not work in your printer. Modern printers automatically connect to the internet but pc software or internal printer software (firmware) will often need to be updated at the request of the printer.
These updates can often fix bugs but more recently printer manufacturers have used updates to stop compatible cartridges from working in your printer. Often delivering messages like ‘cartridge not compatible‘ or ‘Ink cartridge not recognized,’ or ‘cartridge empty‘.
Remanufactured inks can have an empty status set to the chip data which means you need to bypass the error.
