This update helps to recognize compatible cartridges or continuous system with self-resetting chip that I stopped recognizing due to firmware update in Epson WF-7510 Printer.

You saved me a ton of money. This is the second time I had to reset a printer's waste pad, and Wicreset has not disappointed me. Thank you, thank you, thank you!

I spent 4 hours trying to get my r340 to work then l I used your program to reset the protection counter. I have just printed 5 pages and 4 disks. Slightly cryptic instructions but it worked perfectly. it took me all of 5 minutes.

I tried using the free utility Epson provided, the counter reset to 40%, then after a print I got the error again. I gave WIC a chance out of desperation and it work! Saved me from throwing out a perfectly good printer and buying a new one. I use CISS and do a lot of prints and head cleaning. I cleaned ink pads myself but will set up a waste bottle when I get the chance.

THIS IS A MUST HAVE UTILITY This reset key worked perfectly for my Epson Artisan 800. I tried the Epson reset utility (free from Epson) many times. It would "reset" the counter to "40%", then upon turning printer off - on, it would revert to "0%" with the error message that the inkpads had reached their end of life. This also happened whenever I performed a head cleaning. For those of us who use a CIS (I am not affiliated with inkproducts.com - but have been using their CIS for a couple of years and LOVE the quality and service) - it is imperative to be able to reset this waste ink counter. I should also add, the waste ink pad issue is real - don't expect to simply reset the waste ink counter and go happily on your printing way - you will have a disaster and you will experience frequent head clogging. You MUST use an external waste ink disposal system - either make your own for $5 or buy one. THIS + the reset utility is what enables you to get the true value from your CIS-modified printer.
