  Thanks for your advice. I had the printer Epson Pro 4900 attached to the network. Once I used the USB connection everything worked great. There were 2 ink channels that I could not clean. After poking around the internet I found discussion of air in the lines. Did an initial charge and now things are working perfectly. Thanks for a great product and tech support. Regards, Morris Gven

  Veramente efficace e veloce. Sono più volte che utilizzo il programma WIC e mi sono trovato sempre bene. Certo, bisogna svuotare la vaschetta di recupero dell\'inchiostro. Se no...

  It is end of October 2021. I just have bought the second reset key in my printers life. The first one I bought in 2015 !!! That means my printer had already it's life prolonged by 6 years and goes now into the second reset cycle. Keep up the good work to prevent valuable electronic hardware becoming garbage. I never had any trouble in 6 years with the ink waste pad after resetting the counter for the first time.

  I had a G3400 with the 5B00 error. I purchased the Rest Key and I am printing again. Thank you very much...

  Printer is now fixed and working fine. Thank you very much for your help. (I have already \"recommended \" your site to a friend who was having a problem with his printer. Further if (when) I have a problem with any of my other printers, (Canon S600 and Cannon i560), if a manual is needed, I will revisit.
