Small glitches but renews printer to like new.
Color: White Ink Pad 2xin
Makes the printer work like new, the software works well but I had to run the routines several times before the printer actually actually cleared. Now it works like a new printer.

Really want an Epson Printer?
Color: White Ink Pad 2xin
Buyers get prepared for hours of frustration if have an Epson Ecotank printer because this seller does not tell you what's ahead when buying this product. One's instructions are vague and come with hours of frustration. Forget those U-tube videos they too only want to make small talk, you either buy this product and put up with hair-pulling software, or go directly to Epson and buy direct either way this will make you not want to buy another Epson product. Change out the Ink Pad reservoir in the back of printer at corner behind the ink tank. Will need a small Phillips-head driver (this kit comes with driver) to remove cover, once cover removed remove the ink pad attachment screw, save those screws for reinstalling new ink pad. Now comes the fun part resetting that E-11 Error shown on printer screen. Until this is resolve you will not be able to print anything. Before you get started with the given weblink nothing will not work until you turn off the Wi-Fi and connect printer to computer via USB cable; and, most printers do not come with that cable must buy on Amazon separately (under $5.00). Once cable connected check to make sure have a good connection from the Device Manager. Now clear out all pending print jobs. Then download the weblink shown in the instructions; do not even mess with that Driver and Utility Combo Pack (why instructions shows that who knows why...) just download www.wicrestpro.com then follow instructions; and, if you get a communications error you did not follow these steps in order. When you see Epson Adjustment Program click on the Port you will see selections (Auto Select and multiple printers locate your printer and click on that printer then click OK. Next screen click on Waste Ink pad counter, and make sure on next screen you don't go snooping around, just check all 3 boxes and click Initialize then here is when WTF may or not occur. When the OK button is clicked, counter will be initialized, and you click OK. If you get a Communication Error don't panic go back into your computer setting make sure Firewall for printer is off, Wi-Fi is off, Virus Protector is off, and remove "all pending print jobs" then make sure printer to USB cable is connected firmly. Then go back through same process most likely you will not get Communications error again, but a message reading turn off the printer then after turning off click ok, wait count to 20 then turn printer back on, install paper then click print test page. That's it you have now successfully installed the Ink Pad Counter.

PLEASE BE PATIENT
Color: White Ink Pad 2xin
OMG, this took me almost 2 weeks to get up and running. I followed all the instructions but still couldn’t get it to work. I even contacted Epson, and they told me it might be a hardware issue and that I would need to take the printer to one of their repair locations. I then contacted the seller, who tried to help by providing additional instructions, but I still had no luck. Eventually, after connecting the USB cable to another computer and carefully following the steps again, I was finally able to reset the waste ink pad successfully. It was definitely frustrating, but I’m grateful it finally worked in the end. I really love my Epson eco tank, it saved me a lot of money on ink with different brands so I’m ecstatic!!!!
