  I want to know this program before i buy it. Can you explain me about your program i had many proble..

  Wow, this software really works! I was very reluctant to purchase the reset key, but after taking a few minutes to read all of the instructions and figuring out how to prepare the printer and computer...it was a breeze. Thank you for saving my printer!

  Thank you for your service. The process was straight forward, thank you.

  brilliant - absolutely brilliant. Thank you. Thought I would have to trash my printer and the unused ink cartridges. Only hiccup was needing to disable my security protection to install this wonderful product. Used it as a trial - which proved it worked - then bought the key to finish the job. I am wrapped as you have saved me hundreds of dollars as there is nothing wrong with the quality of the printing. Cheers, Alan.

  I was a bit unsure about trying this at first but thought its only about fiver so give it a try, and i'm glad i did, it's so simple and you save money as well, i had a slight problem with the reset key at first so i e-mailed 2manuals, They sent me a new key and i was all sorted in less than no time . I would highly recomend,worth every penny. David Morris, Gwent, South Wales u.k

  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! :)
Thank you for this wonderful utility!

  Program is easy to use, with the additional manual for reference. It allowed me to correct a corrupted EEPROM in the printer. All the .prn files are missing, so setting up the printer/scanner and the final print check are not possible. If you only want to reset the ink pad counter then there are cheaper/ free program available. Would give it a GOOD rating if missing files were included.

  Thrilled to bits - I thought my trusty printer was destined for the scrap heap ( although nothing wrong except it would no longer operate due to "ink pad full") and I would have to buy new, until I alighted on your product . Also if the ink pad actually causes problem tyou advise where I can buy a replacement kit and do it myself. You perform a great service to printer users. Well done!
