  I have modified the firmware of an Epson wf3620 with the firmware key to make the printer run with chipless ink cartridges. The instructions were clear but must be followed exactly in order for the process to be successful. I am very happy with the result as I have the freedom to use oem ink or not depending on my needs. No oem cartridges now work perfectly well. Well done wic utility people. regds, Peter.

  It work great! But it like I\'ve force to buy because I\'ve no option. Price should be lower.

  When my printer quit working, I ordered a new printer. Then I decided to check youtube to see if anything could be done other than taking it in. That's when I found WIC. This process was so easy, I cancelled my order for a new printer and fixed this on in less than an hour. I ordered new pads and entered the code to reset. Code cost me less than 10 dollars, and 2 sets of pads for 15 dollars. Better than iver 300 for a new printer.

  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.

  This is like Magic!! I decided to leave a positive review because it saved me so much time and heartache. I needed to finish a lastminute order and of course that's when my printer decided that my ink pad was full. I was panicking cuz I only had a couple hours to complete the order. I took a deep breath read and followed all the instructions from here and within five minutes my printer was printing again!! Thank you!! Will definitely come back when/if it happens again!
