If you've replaced the heads, or removed/re-installed them, you need this! Also does a power nozzle clean - worth the money just for that. Note it needs DOS or a DOS box in Windows.

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.
