  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!

  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.

  Very simple to perform on my Epson ET 2760. I received the ink pad reached its end-of-life error message on my printer. I replaced the Maintenace box and then used the reset key I purchased, and it seems to have fixed the issue.

  gracias me salvaron la vida para los que no se han dado cuenta cuando nos pide la clave y es nuestra primera vez pongan la palabra \"trial\" sin comillas y eso soluciona por lo menos por un tiempo
