Good day. I have to clean my printer head EVERY hour. Then it prints fine. Until I leave it for an hour. So this leads to waste pad full and I have to purchase a key every time. Is there another way to go around this problem please? I cannot afford to buy a key every week.

You have to make 2 things
- clean parking station first - then inks will not dry on printhead;
- use high quality inks.

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 R2880 stopped printing and showed alternating ink and paper flashing lights. I had an extended warranty that I purchased with the printer but because I didn\'t register the warranty within 30 days I was told by Mack Camera that they would not honor the warranty. So after much research and web surfing I found myself at 2manuals. I wasn\'t even sure that the wic was the problem and I had serious doubts about spending more money on what could just be another scam like the extended warranty was. However like one reviewer said, what was $9.99. Well I downloaded the program, obtained the $9.99 pin code, loaded the software, and exactly as the video shows I was up and running. I couldn\'t believe it when the printer sprung to life and was ready to print. Hey, try it. You\'ll be glad you did.
