I spent 4 hours trying to get my r340 to work then l I used your program to reset the protection counter. I have just printed 5 pages and 4 disks. Slightly cryptic instructions but it worked perfectly. it took me all of 5 minutes.

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.
