| Patrick Blom Bachstein | 2016-02-25 19:28:33 | So had my Epson Pro 4900 disconnected from powersupply for about a month and a half, due to new facilities in my studio. Powered it up, printed a nozzle check, and banged my head against the wall! Only magenta and light cyan did appear, and two broken lines of photo black. Did the Windex trick 5-8 times, and at the 16. nozzlecheck, 9 colours appeared, BUT some actually has got worse, the more Windex the head had.
Preparing myself on making a stronger brew for the cleaning (a lot of Googling and reading!), I came across the Service Program. Reluctant to spill ~ 150 ml of ink, I first moved along (also, the website seemed shady, however, alot of mentions on various foras).
Today I decided \'What the heck, 30 bucks, if it doesn\'t work, I\'ll survive\', so I purchased a license, installed on a laptop (with USB connection instead of network), and chose the option to prime the left channels first - and WOW: EVERY nozzle on that side now fired, and made an (99%) perfect nozzle check. So did the other side, when finished filling the lines again.
So: 5 f*cking huge stars from me! :)
Thank you for this wonderful utility! | |  | Priscilla Villalobos | 2020-07-23 13:18:55 | | Good morning.
I have two questions, if you´re so kind to help me.
1) The expiration date key. Does it mean once we get it, we have a period to use it? Or what the expiration date referenced to?
2) If the printer has a problem and we have to format it again, will the key information lost and we need a new one, or does it be able to be used again?.
Many thanks !
Esther | | | Igor Dimovski | 2011-09-24 01:53:10 | | my Epson P50 worked again with sharm,thank you 2manuals.com | | | Sherrylee Abrejera | 2021-02-19 04:48:05 | | Hi, I want to ask how will I know if my printer can be modified to chip less printer. I have an Epson 4730, I purchase it last year September but I am trying the compatible cartridge on it but it didn't work. So I am worried that if I buy the activation key, it will not work too. | | | daren roberts | 2011-09-03 23:57:10 | | Perfect seriously i look and tried everythig to reset my epsonR285 within seconds this done the trick
Fantastic totally fantastic
Thank you well worth the money never thought this would work cool | | | Paul Jumbo | 2019-04-19 18:47:57 | 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. | | | Russell Thielemann | 2016-06-29 09:28:59 | | An excellent service that works. Don't be fooled by the printer manufacturers that you are trapped into buying their over priced cartridges because you thought you were doing the right thing by upgrading the firmware. The only reason for their upgrade was to stop you from using your own cheaper 3rd party ink cartridges. If you accidentally did do the upgrade as they recommended don't worry as you can undo that costly mistake with the help of "wicreset". It really works. Also did you know that 3rd party cartridges actually contain around 25% more ink than oem cartridges? | | | Palais Lützow | 2025-01-10 14:57:50 | | Hello! I tried several times to reset the WasteInkIndicator on our ET-2720 without succsess !!
