It worked fine. It was just that we didn't know where to start with opening the program. I couldn't get it to install so there was an icon that took us into the whole program. I found out that if I clicked on the one icon it opened the one we needed. The service manual will be of great help for later when the ink absorption pad needs changing. Thanks for your prompt attention. Regards, Ruth

Printer EP-806AW I bought a clear key because there is a limit on waste ink. It was very helpful because I was able to solve it safely.　Thank you very much.　 （JAPAN　2020/11/07）
