| eugen niculescu | 2006-05-24 21:19:42 | | Worked perfectly! Thanks! | |  | Darren Townsend | 2020-10-14 21:53:29 | | I purchased four activation keys total, but I had an issue using one. John at tech support got it straightened out and I was able to complete the install on the printer. Now I can set up the CISS unit for Sublimation printing. I'm very happy, and can testify that this product works to unlock the firmware of your printer.

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! | |
