I was a bit unsure about trying this at first but thought its only about fiver so give it a try, and i'm glad i did, it's so simple and you save money as well, i had a slight problem with the reset key at first so i e-mailed 2manuals, They sent me a new key and i was all sorted in less than no time . I would highly recomend,worth every penny. David Morris, Gwent, South Wales u.k

it does not work, can not recognize ink cartridges always displayed, Epson SX400 ========== REPLY ============== The WIC reset utility can reset Waste Ink Counters only. Not Ink cartrigs levels in SX400. You can use auto reset chps to reset the ink levels.

I just downloaded and tried your WIC Reset Utility. Since I am running Windows 8.1 I was afraid that it might not work too well. I was WRONG!! Happily it works GREAT on Windows 8.1! I\'m a happy camper!! Just thought I should let you know!! Best regards, sundar
