| Ron Lugo | 2012-10-17 03:56:00 | | Wow! Your program works perfect under the 64bit environment. You are my savior style in terms of the time and effort.
There is no epson service center in my area. Thank you so so much. I will advertise for you. God bless you. | |  | john Liang | 2018-08-16 18:24:01 | 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! | | | yasuyuki kawasaki | 2020-06-13 17:31:24 | | thanks guys ..i couldnt sort this problem out until i came across your site | | | Patrick Blom Bachstein | 2016-02-25 19:28:33 | So had my Epson Pro 4900 disconnected from powersupply for about a month and a half, due to new facilities in my studio. Powered it up, printed a nozzle check, and banged my head against the wall! Only magenta and light cyan did appear, and two broken lines of photo black. Did the Windex trick 5-8 times, and at the 16. nozzlecheck, 9 colours appeared, BUT some actually has got worse, the more Windex the head had.
Preparing myself on making a stronger brew for the cleaning (a lot of Googling and reading!), I came across the Service Program. Reluctant to spill ~ 150 ml of ink, I first moved along (also, the website seemed shady, however, alot of mentions on various foras).
Today I decided \'What the heck, 30 bucks, if it doesn\'t work, I\'ll survive\', so I purchased a license, installed on a laptop (with USB connection instead of network), and chose the option to prime the left channels first - and WOW: EVERY nozzle on that side now fired, and made an (99%) perfect nozzle check. So did the other side, when finished filling the lines again.
So: 5 f*cking huge stars from me! :)
