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.

The reset utility works great for my Artisan 700. Thank you SO SO SO much for making this available for Mac. You can\'t imagine how much hassle you\'ve saved me - trying to get a Windows machine to run a reset utility on... Excellent service altogether. Many thanks from Ireland!

My Epson R260 quit working- read up online what the cause was (counters in printer). I downloaded the WIC Utility package and sure enough the counter was at 100.70%. I downloaded the Reset Key- at first it didn't work. Turned the printer off & on as instructed. Still didn't work. Finally I turned the monitoring on- reset the printer. Then turned monitoring off again and reset the printer & it finally worked. I think the monitoring just got hung up somehow- computers!!! I'm very thankful I'm good for another few years. It only cost $9.99 instead of the price of buying another printer (and I have all these ink cartridges that would go to waste)- OR a repair bill & would be without it while being fixed. Would I buy another Epson printer- NO- but would I recommend 2manuals for the fix- Definitely.
