  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!

  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.

  This program is a definate must have if you want to service your own printer. Using this program along with the servive manual (440,640,740) will help you to determine what the problem is. The program shows print head voltages, waste ink counter and reset, and recover print head functions just to name a few of the useful functions that this program has to offer. It returned my printer from a paperweight into a working Epson 640 in minutes. Even if your printer is working properly you can use this program ensure it will keep working. For less than $6.00 it is worth having.

  thanks for you give my software if you want helped call me now
  Farhan Hossein 2018-03-04 06:43:56  
  Nevermind. Did more research and to resolve the error, aside the firmware downgrade, I removed the ink, unplugged the printer, turned the printer back on, and placed the Ink's in individually pressing done after each ink. Doing this I was able to get it back up and running again. Thanks!
