My printer stopped printing with the error as \"General Error\" Epson quoted me $60 to send an engineer to fix my printer. After reading through the information on this site I decided to fix it myself. Found the problem was related to the waste ink pad counter. Only 10 minutes, I had the the printer working. The printer tested fine and has done approx 150 pages since with NO issues. Thanks!

It works. Just purchased a one time counter reset license for my Epson L380. Immediately after payment with credit card (electronic version for web shopping) , I got the key number and used to reset the printer. Worked like a charm

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!

The process of resetting my printer after replacing the ink pad was so incredibly easy. The instructions were very clear and my printer reset immediately

It works perfectly to make Epson XP-55 chip-free and disable ink levels. Many thanks.
