I took a gamble last week by buying a Epson Pro 4900 for less than $140 thinking if I could not get it going, I can at least take the remaining ink out of the cartridge and use it on my other printers. The initial nozzle test was not so bad for a printer that was unused for about 1 year, I got six Nozzles firing at around 90% not bad, the next thing I did was the popular Windex treatment, I ran 4 sessions of Windex treatment on the printhead, first one lasted 1 hour, second one lasted 2 hours and third one lasted 4 hours and the last one lasted 8 hours, I got a fully soaked paper towel in my last two treatments, I ran a series of power clean on the non firing nozzles but the Green nozzle remain clogged. At this stage I thought this program may be my last chance to rescue this printer. I bought the program at 6 pm today, I ran the CL1 clean on OR/GR channel and the green nozzle remain clogged, I then ran the CL2 clean on the same nozzles and the same result, at this point I thought maybe this printer is completely dead but I will give CL3 a shot, I went for dinner when CL3 clean was performed on the printer. I came back immediately printed the nozzle check I got the perfect Nozzle pattern on almost every single colour nozzle except Cyan which has a few bar missing, a quick CL1 clean on Cyan/Magenta fix that. The next thing I did was to run a quick paper profile on this printer with X-rite software, I printed two test pattern page to calibrate the printer, then come the first real print on my Epson Stylus Pro 4900 it was absolutely brilliant, the best printer I have ever own and the IQ on one of the cheapest glossy media I could find was simply breath taking. I have to say without this software my $140 purchase would probably end up in the rubbish dump. I must say I was skeptical about the truthfulness of the success that other has with this software but with myself actually tried this software, I have no reservation but to recommend that anyone who has a clogged Epson Pro 4900 to give this program a shot it may just save your printer. On the scale of 10 I would probably give it a 11 and it is more than just good!

i reset with the key that i got and nothing worked. it still shows that the carts are not genuine. what a waste of time. it sat here for 12 hours on the "do not turn off printer" epson wf-7210.... give me back the $30 i spent or give me more keys to try again. order #18740047 =============================== According to your Order number - You have purchased RESET Key ($9.99) which is required for Wate Ink Counters reset. If You want to downgrade firmware - You have to buy FIRMWARE Key ($19.99)

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
