| arbin zamora | 2022-12-30 22:58:51 | | Just wanted to say thank you for a most helpful product which does exactly what it says. Followed all instructions, replaced waste ink pads and we have a working printer again. For very little outlay.
Congratulations on running an excellent business.
Have a good day, | |  | Ivan Tilbury | 2015-09-08 06:01:35 | I purchased the epson adjustment program last night and got to work on it today.
I had a clog in C and it would not clear. I ve had my 4900 for over 2 years and have been able to handle them until now.
I learned about this site from another site that has cleaner for the 4900 and said I need to buy this software first. I bought it and tried it with the epson ink that was in my printer. I ran the adjustment and it cleared C but then there were other clogs. Because they werent clogged before I started, I cleared them the normal way through the printers options. Had they not cleared, I would have ran the adjustment again.
I had tried everything to get C to clear for a week and this program did it in one try!
I would highly recommend this for clearing a stubborn clog. And now it is in my arsenal if I get another one that I cant clear down the road. By the way, it does not work if your printer is networked. Mine was so I had to move a computer into the room with my printer, directly connect to it and install the drivers. Then it work fine.
If you got a clog that you cant fix, just buy it. | | | Marc FRANCOIS | 2024-12-11 16:29:30 | | 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 | | | Frank Topping | 2011-02-24 20:39:33 | | I'm not going to lie I was very dubious, but the proof is in the pudding it does work and I'm a happy bunny. My printer is the Epson Photo PX810FW one of the newer models so feel confident in using this system. | | | GENNA SHOES | 2025-06-14 11:16:01 | | ho ordinato 1 codice online, il codice รจ arrivato subito tramite mail, l'ho applicato alla mia epson et-4700, ho spento e riacceso la stampante ed ora il contatore segna 0%, ottimo!!! Grazie!!! | | | josue montoya | 2017-02-12 16:51:56 | Epson Stylus DX4400 is not supported, and it seem to be impossible to reset the waste counter.
