  I purchased four activation keys total, but I had an issue using one. John at tech support got it straightened out and I was able to complete the install on the printer. Now I can set up the CISS unit for Sublimation printing. I'm very happy, and can testify that this product works to unlock the firmware of your printer. (Epson WF-3720)

  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.
