This small program resets numerous factory locks on Epson tank printers listed above,  such as the "Replace ink waste pad error" which was a big headache for me, until I found this program. It also does other things such as print head alignment, ink reset levels, nozzle checks, and other repairs. I'm uploading this because I hate it when printer companies do this to their products. Just unzip and run in Windows. Worked for me on Windows 7
