| Evgen Test | 2010-08-31 09:40:59 | | My printer stopped printing with the error as \"General Error\" Epson quoted me $60 to send an engineer to fix my printer.
After reading through the information on this site I decided to fix it myself.
Found the problem was related to the waste ink pad counter.
Only 10 minutes, I had the the printer working. The printer tested fine and has done approx 150 pages since with NO issues.
Thanks for the WIC program! | |  | philip haynes | 2010-01-04 01:28:00 | | Excellent! Thanks. All working nicely now!
One happy customer
- philip | | | Rick Benavides | 2011-06-07 22:14:16 | | Thanks John,
You saved me alot of time and frustration dealing with that idiot I was talking with at Ebson, he didn't know sh$t about my printer, he began by telling me that my printer was like a human body and I was like WTF???, well anyway I eventually told him he was stupid and hung up on him, I called the place where I purchased my printer from and he gave me your website, everything is working fine now and you saved me from any down time I would have had taking to the service center!...thank you again! | | | Linda S Perkins | 2018-02-15 12:00:09 | | Wow, what a program, it just reset my Epson WF 7525 with inkpad problem.
Thank you!
Max | | | adrian dionisio | 2017-03-06 20:18:29 | | Everything works good for resetting printers. I hope the developer would ad Epson WF-3620 too. I use wic reset utility whenever I do repair on printers. Hopeful that the developer would add my very own printer WF-3620 on the list. God bless to the maker and developers of wic reset utility | | | 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. | |
