  An excellent service that works. Don't be fooled by the printer manufacturers that you are trapped into buying their over priced cartridges because you thought you were doing the right thing by upgrading the firmware. The only reason for their upgrade was to stop you from using your own cheaper 3rd party ink cartridges. If you accidentally did do the upgrade as they recommended don't worry as you can undo that costly mistake with the help of "wicreset". It really works. Also did you know that 3rd party cartridges actually contain around 25% more ink than oem cartridges?

  I was tearing my hair out trying to get a solution for my Epson R265. Other solutions didn't work and were not compatible with Vista Home Basic. The WIC Reset Utility worked like a charm! In just a few moments - I'm off to buy a waste ink device so I can get a lot more service from my machine.

  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.
