Brilliant stuff! Have tried everything over the last few days to reset my R265, and finally found your site! Brought a key, bit of a problem with my email account, tried another one, got the key, reset the R265 AFTER washing out the inkpads, now everything is working as it should. Many thanks.

Hi, I'm particularly satisfied of the Wic Reset Utility I just used for the 3rd time (2020, 2022 and now) for my Epson WP635 Printer. I had felt pads left from the last time, easily replaced them thanks to the excellent instructions found on octoink's site, then bought a new key and re-intitialized my printer in minutes. My printer is now renewed for 2 years! Very very satisfied. Many thanks. MF, France

OK Im here because Youtube directed me here to fix my Epson ET-2803 printer! I've downloaded your APP and tried to use it! ...There are a number of problems!!! ...First off, couldn't you find any smaller text!!?? Trying to read and follow your directs is near impossible! Next up, your directions aren't very clear! You direct me to turn on my printer then to turn it off. And as I try to move forward I click on your direction and NOTHING happens, until the command times out. BUT IF I turn off my printer again (un-directed by you) the command tried to go through. UNTIL I get more directions to turn on my printer and not turn it off again. I've seen a line at the bottom of the screen there a line of text floats through saying that the computer has been reset per the Youtube site I'm supposed to get a congratulations of a successful at the finish, I never get that, because my last command (theoretically) never goes through, again just sitting there until it times out again. IF your really trying to "help" people PLEASE fix you site! Because nothing seems to work correctly, I'm hesitant to buy any keys from you. ...Sincerly, Mark L
