  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.

  Great product, once I had the key the problem was sorted in less than 5 minutes Thank you, Billy @ PISIFI

  I have been struggling with a clogged head on my Epson Pro 4900 for weeks.
The Windex-on-a-papertowel-overnight solution has worked before; however, it was not clearing the nozzles this time.
Thanks to John\'s link ( ) for guiding me to!!
I purchased the SP4900 program and it was GREAT!
I used the Adjustments (Individual) program on Section 2 Head Related Checks and Adjustments, first at level CL3 then CL2 for the clogged colours channels and voila, my head is now fully functional again.
I have only browsed through the other SP4900 subroutines, but they will provide me with a full suite of maintenance routines that could be very useful in the future.

This program was fantastic. The only inconvenience was that it is a Windows .exe file and I am a Mac OSX user. I had to launch Windows 7 Pro in Fusion and conduct the maintenance; however, with so many Mac users needing this type of help for the Epson Pro printers, it would be great to have an OSX program option too. That being said, if you can run Windows on your computer and have an Epson Pro 4900, I highly recommend this indespensible program. At $29.99 it is a steal compared to calling in a technician.
Keep up the super product support, John!! Thanks.

  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

  Very helpful - thank you. I was stuck as I use a Mac and your Mac software saved the day. I used the trial key this time to be sure it worked, but will be happy to purchase one when I need it next.
