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.

Thanks for the program and manual. I was able to revive a 2 year old 4900. I had 100% blockage in 8 of the 11 heads, and over 50% blockage in the last three.... I ran the ink charge with cleaning fluid. Now I have 100% of the nozzle check pattern on ALL of the heads. I was blown away. I thought for sure I was going to pay for a new head. So, thank you. I also have a an older Epson Stylus Pro 4000. It has been sitting a while and the heads are dried up. Do you have the same program and manual for this printer? I would like to try to revive it as well. If you do could you just send me a link? Thanks again
