Alan Page | 2017-07-23 03:33:02 | brilliant - absolutely brilliant. Thank you.
Thought I would have to trash my printer and the unused ink cartridges.
Only hiccup was needing to disable my security protection to install this wonderful product.
Used it as a trial - which proved it worked - then bought the key to finish the job.
I am wrapped as you have saved me hundreds of dollars as there is nothing wrong with the quality of the printing.
Cheers,
Alan. | | alain dehay | 2011-01-13 01:08:00 | so quick so useful answer in realy good time everything working
thanks mate worked a charm - will definately recommend you to my friends | | Willie Morel | 2005-02-14 13:47:08 | | 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. | | NACHO GOMEZ | 2010-10-25 23:44:48 | I got the flashing lights and Service required message on my Epson R2400, as many others have before!
I spent hours online and eventually managed to download Epsons own
Adjustment Program. It showed me the waste ink settings but would not let me reset the counter, although I had disconnected the feed tubes and re-routed them to an external bottle.
Today I found 2Manuals.com and downloaded their WIC reset program. I thought It probably won\'t work but one key is only $9.99 so what the heck!
Well that was the best $9.99 I have ever spent - as soon as I entered the key and hit RESET the printer whirred into action, ink pumped into my waste bottle and I am back in action!
This has saved me a lot of money and the hassle of sending the printer to an Epson service centre. Truly a 5***** product! Chris Porteous, Prestatyn, U.K. | | NAREN NAREN | 2009-05-05 19:38:21 | This is what I need. Thanks. | | star link | 2019-08-31 04:22:56 | Works slick...and why shouldn't they make some $$ for their key and Utility? I appreciate not having to send the printer to Tech support or buy a new one like Epson suggests- when it was a piece of cake to do myself. | |
