I have a Epson TX700w printer I contacted epson in Australia for a fix for full ink pads. They were about as much help as an ash tray on a harley. I pulled the pads out joined a hose to the ink drain hose drilled a small hole in the case put the hose through to a bottle on the out side ink pad problem solved. Downloaded the WIC Reset Programe Reset counter job done. The printer is working like a new one. I will never buy another Epson product again. A big thankyou to the Wic Programe you have saved me a lot of money. Bill.

My Epson XP-800 max'd out on counters and died on me. Screen of death with printer disabled by manufacturers internal firmware. Researched the web and found these guys. The reset process and key purchase was easy to follow and after a few registration steps and a simple paypal transaction the reset key arrived, was entered and the printer was back working again. Saved me at least £80 on a new basic 3-in-1 printer plus ensured my existing ink supplies were not useless Thanks guys - thoroughly recommended

I had Epson WF-2650 and it wasn't printing fully, skipping lines, even though colors were full.
I did a lot of cleaning, head cleaning, put new cartridge but no luck. I did some head cleaning using glass cleaner and syringes as shown on various youtube video.
After that, my printer didn't recognize two of the cartridges. I tried everything, cleaning contacts etc, nothing worked.

I was finally going to buy new cartridges however stores were closed today so I decided to look for chip-resetting tool but nothing good was available locally.

I came across this WIC reset utility and was really skeptical if it will work. I took the chance, bought the key, used the tool to reset firmware to chipless firmware, it was successful at the first go.
At this point, printer showed all ink levels 100%. I printed a test page and it came out perfect.
To make it even more interesting for me, I live in Europe and during one of the trip, I bought two sets of XL cartridges for this same model but printer didn't recognize in the past and I was going to throw them since these were no good for my EU model. I tried these again after chip reset firmware and voila, they works too.

I am amazed at the propaganda of these printer manufactures that even original printer cartridges from US didn't work on the model here in EUROPE, these used to fit perfectly but printer wouldn't recognize however, now they works too.
Today, I was almost ready to trash my 2.5 yr old and not much used printer but after a lot of trying and finally using WIC reset utility, the printers works like new and saved me a lot!

These were the best 20 CHF/USD I spent today!
Thank you very much and I don't need to worry about relying on a hardware chip-reset tool. I will now be able to use US model cartridges and re-fill i like without having to worry. I even printed some photos using this same printer on photo paper today and printer did an excellent job.

I don't like throwing something (a printer in this case) away and consuming our earth's resources (buying a new printer) just because Epson make it difficult for me to avoid doing this. I wish Epson would make products that can be maintained by the product owner and this way contributes to the well being of our planet. This reset utility worked 'as described' and now, having cleaned my ink pads, I can get more value from the printer I already own. Thanks for this reset software.
