Identifying the Issue

You may have recently replaced your computer or reinstalled the printer, only to find that after the firmware update, your third-party ink cartridges are no longer recognized. This can be frustrating, especially if you have a surplus of third-party ink cartridges.

Finding a Solution

Fortunately, there's a way to revert to an older firmware version that supports third-party ink. The process involves downgrading the firmware via a USB cable and keyboard shortcut on the device. However, the challenge lies in locating the older firmware version compatible with your Epson WF-3520.

Locating Older Firmware Version

The firmware version CG29CA (29/10/2012) is known to support third-party ink on the Epson WF-3520. However, finding a download link for this specific firmware version can be challenging. Despite conducting a Google search, many users struggle to find relevant results.

Downgrading Firmware

Once you've managed to obtain the older firmware version, follow these steps to downgrade:

1. Connect your Epson WF-3520 printer to your computer using a USB cable.
2. Access the printer's settings menu.
3. Navigate to the firmware update section.
4. Select the option to downgrade firmware.
5. Follow the on-screen prompts to complete the downgrade process.

Community Support

In the tech community, sharing resources and solutions is essential. If you've successfully downgraded your firmware or have access to the older firmware version, consider sharing it with others facing similar issues. Collaboration can streamline the troubleshooting process and alleviate frustrations for all users involved.

Preventative Measures

To prevent future firmware updates from interfering with third-party ink recognition, consider implementing the following measures:

1. Disconnect the printer from the internet to avoid automatic firmware updates.
2. Regularly check for firmware updates manually and research their implications before proceeding.
3. Explore alternative printing solutions that offer greater flexibility with ink cartridge compatibility.

Navigating firmware updates and printer compatibility issues can be challenging, but with the right resources and community support, solutions are within reach. By downgrading the firmware of your Epson WF-3520 printer and taking preventative measures, you can regain compatibility with third-party ink cartridges and continue printing hassle-free.
