Absolutely fantastic. I got the error message and removed the ink pads ans washed them, don't think I got all the ink out though! Then I used this program as a 'trial' and it worked wonderfully, Printing all OK again and I thought I would need to buy a new printer. When it happens again, I will purchase new pads and a reset key - has to be cheaper than a visit to a repair shop or a new printer. Thank you so much

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 just bought five keys and used the first one. It magically worked. Epson XP-422 is back to life. I also took advantage to clean the waste box. This is also important :-)

This program is a definate must have if you want to service your own printer. Using this program along with the servive manual (440,640,740) will help you to determine what the problem is. The program shows print head voltages, waste ink counter and reset, and recover print head functions just to name a few of the useful functions that this program has to offer. It returned my printer from a paperweight into a working Epson 640 in minutes. Even if your printer is working properly you can use this program ensure it will keep working. For less than $6.00 it is worth having.
