  I was ready to trash my Epson 1400 but decided to give 2manuals.com a try. I purchased the usb sender tool and firmware upgrade as well. Had my printer fixed in minutes! Great work and products! Anyone out there that is thinking of trying the products offered here but are hesitant, don't be. There stuff works. Regards, Forrest T.

  Great software! Helped me out most when i needed. Downloaded software and used the trail key and instantly reset my printer, will definitely purchase key next time when needed. Thanks

  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!
