After resetting your Epson L3210, verify that the process was successful:

: Connect your printer directly to your computer using a USB cable . The resetter will not work over Wi-Fi.

(e.g., from “ITkoding” – a site that may provide printer utilities), I cannot provide links or direct downloads. I recommend searching for “Epson L3210 adjustment program” only from reputable sources, and always scan files with antivirus software.
