This little app is a life saver. Got up at 6 am this morning as I needed to print out some important documents for later today, only to find that all the lights were flashing on my printer. A quick search on the web pointed me to this site and the app informed me that my ink pad was full. A few clicks later and my printer is like new again. Many thanks.

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,

Thank you! I paid less for my Epson R320 1 year ago than Epson want for servicing it. I had printed a head a nozzle check 2 days ago when I put in a new cartrige all printouts were perfect but today my Printer told me it needed service and refused to work. Your fix showed me two things the Ink wells did not need flushing as stated by the Epson Tech and that my printer had been set to only run half the usual plates so that was why the service notice cam up so soon after I purchased it.

Ce logiciel a le mérite de fonctionner en WiFi. On n'a donc pas besoin du câble USB. Pour 8.54 € (9.99 $) j'ai facilement réinitialiser les compteurs de mon Epson XP-610 qui était bloquée. This software has the advantage of working over Wi-Fi, so you don't need a USB cable. For €8.54 ($9.99), I easily reset the counters on my Epson XP-610, which had frozen.

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.
