  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!

  Oh my golly, I didn't think that would work, but it fixed it in about 30 seconds. Even though I hadn't been able to disable the process monitor thing that it says do first, the reset program still worked instantly when I ran it on an Epson XP-540. If there is one thing that gets my goat in terms of being so unethical both a rip-off financially and environmentally unsustainable, its the way printer companies rip us off. So am super grateful to have found a way round this. For a much more reasonable price than the printer shop told us, and something I could do at home when I needed the printer urgently for work! Thanks so much!

  I have modified the firmware of an Epson wf3620 with the firmware key to make the printer run with chipless ink cartridges. The instructions were clear but must be followed exactly in order for the process to be successful. I am very happy with the result as I have the freedom to use oem ink or not depending on my needs. No oem cartridges now work perfectly well. Well done wic utility people. regds, Peter.

  Perfect: reset an Epson XP-700 counters within a minute. Worth 10$ :)

  My Epson Stylus R280 is printing again! This was my favorite printer for photos and quick single-sided jobs. It printed and printed until the dreaded message and alternating flashing orange lights appeared.

I was skeptical that WicReset could do anything because of the flashing lights. I downloaded the Windows version (XP), virus scanned it and after it passed, installed it. I first tried the trial reset that sets the waste counters to 90%. That worked immediately. I bought a key. That worked immediately and now my printer is working like new and waste counters are near 0.

I use a continuous ink system (CIS) on my Epson printers... have for years. This software also has a nice utility to charge the cartridges and clean the heads. My R280 printer sat for a while after the counters reached limit and the ink lines filled with air. I used the WicReset utility to charge & clean, and now it prints like new.

This software is easy to use and guides you step by step. I encountered no difficulties and everything worked first time. It is very good that there are smart engineers out there who took the time to reverse-engineer Epson\'s awful ink pad limitations.

One note of caution, and this has nothing to do with WicReset... I print so much and fear my ink pads will truly overflow, so I\'ll be installing a waste ink tank on my printers. I had one on an ancient R200 printer and it worked great. This is an essential accessory for CIS printers.

Thank you WicReset.
