UPink C9345 Maintenance Box chip Resetter Compatible for ET-5800 ET-5850 ET-5880 ET-8500 ET-8550 ET-16600 WF-7310 WF-7820 WF-7840 EC-C7000 WF-7830 ST-C8090 ST-C8000 L15150 L15160 L6570 L8168 L8188

Very easy to install, great fit and perfect for the value of your money. Worked well with my printer.

This little dude saves me a lot of money! I know it's expensive at first but it is well worth it! It works every time!IMPORTANT HELP: My chip resetter wasn't working but I have had mine for almost a year and this was the first time I have ever had this problem. I hooked it up to my phone charger USB cord for about 5 minutes, then tried it again on my maintenance box and it worked perfectly. Another thing to try: If your light stays red and you have the pins and contacts aligned, try to move it just a tad bit while on the contacts as sometimes it will be off just a little hair and will cause it not to work. Hope this helps someone!

Worked with no problem

Was so happy to order and receive this but it never worries me AT ALL I tried several times but couldn’t get it to work. I had to order a new waste box for my Epson et-8550 so that I could print. That light stayed on red never went to green. What a waste of $40

Definitely a money and time saver. I no longer have to purchase maintenance box or wait for them to be delivered. Product was easy to use and works perfect once you line the pins up correctly. Worth the purchase

Works great

Overall the resetter works as indicated. The maintenance box shows empty when I use it. The only issue I'm personally having is that when I use the box I reset, I get more ink output causing splotches and I'm unable to run a satisfactory print test. I run the cleaning 2-3 times and it does not help. I use the regular maintenance box and my ink output is back to normal. The end result is not what I expected.

Using with Et-8550. Seems to work well
