  My Epson 1280 started getting the dreaded flashing panel lights. The printer quit working all together. I found on the web, that the cause was the ink waste counter had topped out and the printer required service to reset the counter. Then I found this site and downloaded the manual and the service application. Ran the program and quickly reset the counter now all is well again! Worked like a dream. Thank you! Art @

  I was a bit dubious about buying and downloading manual, never having used this site before, but I'm glad I did. With it I was able to sort a problem on my printer. Without it I wouldn't have known where to start. Thank you. Steve Goodey.

  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

  All I can say is thank you so much for saving my printer. I changed the ink pads ( very simple task ) and used the Epson Reset. My printer still did not work and I was devastated. I spent MANY hours online researching the problem ( Epson was absoutely no help at all ) and finally came across your product. I used your program to reset the ink pad counter and it reset the counter as advertised. After I restarted the printer It would not do anything. I uninstalled all of the Epson software and reinstalled with the original disk that came with the printer. AWESOME a new printer!!! I can not tell you how much i appreciate your product! I thought I was buying one of the best printers on the market at that time and I am really TICKED off at Epson for building in an unnessisary self destruct. I had purchased every upgrade for my printer Epson offered and was determined to get it working again and you did that for me. THANK YOU !!!!

  Epson has a new printer. XP-15000. It would be good if we could reset the waste ink for it.

  I ordered from you the service manual for my R2880 printer which showed me that I needed the adjustment program which I also ordered and now my printer operates correctly again!!! Thanks

  I bought refillable cartridges for the Epson XP-241 on AliExpress and did not work. The reason: Epson XP-241 manufactured in the Philippines. I was desperate. The solution: CHIPLESS. You've saved my XP-241 printer. Thank you very much.
