Description

Chipless Firmware Conversion Kit (.BIN): Epson WF-78 Series to L15150 / ET-16600
Unlock limitless printing and eliminate cartridge errors forever.
This digital firmware package provides the .bin files required to permanently convert your Epson WorkForce printer (WF-7820, WF-7830, WF-7840, or WF-7845) into an EcoTank L15150 or ET-16600. Once the modification is complete, your printer will operate fully "chipless," meaning it will never again ask for a cartridge replacement, reset, or chip check.
