  Is this Adjustment program compatible with the USA Destination? Initial setting was designed for 127 cartridge? Thank you.

  Sure wish your live support was online. I could understand it being down on New Year's Eve, but not today. I sent an email to this effect also, but no reply. The reset key worked, thanks. For just half a day, however. Not what I expected for $9.99. Please advise.

  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!

  This was awesome. I was skeptical at first, but the program worked beautifully. Thank you for helping me, where Epson couldn\'t. I truly appreciate it! Great investment, happy camper.

  I was amazed how easy that was. I was in doubt that this simple download would work... with my heart racing!

I entered the key,and there it was, all fixed.

2manuals, I must say, what you said it would do, it did, and I\'m so relieved and happy, and can work again.

The success of this has made me want to write a review on your product right away.

Thank you so much

  Hello, I've been ripped off like thousands and millions of others, no doubt? I bought a key for Epson XP-2100 without a chip, but it's not clear what to do. I didn't receive any instructions, and the ones on your website contradict each other! I tried to update the firmware, waited a long time, and finally realised that the firmware wasn't updated! What use is the key I bought? And why am I being asked to reset the counter to zero when I want a printer without a chip? What is the wicreset.exe software for? It doesn't do anything, not even generate a report to find out the firmware number... Licensed to : ALEX ANDREOLI
