  Amazing Support, This is what happened, I had to think for more than 4 hours about the purchase and program authenticity. Finally decided to gamble, Registration 1 min Payment instant Call Back in 1 min Mail with key check 2 min Input key in WIC and reset 1 min VOILLA!!! Printer was ALIVE..Again.... Was an amazing purchase. P.S. I do not post reviews for any purchases made unless they are a real pain in the ..., or unless the product is amazing.

  Wow, I cannot believe that this actually worked. I had some issues when ordering the reset key, but i contacted the website via email and they immediately got back to me and sent me the key code. ran the program and the printer now works again. I had tryed the reset utility from epsons website, but it didnt work how it was supposed to, it would reset but when you would go to print it would go back to the flashing inkpad needs replaced. I will have to print for a while and see how long this actually works, but for now this has saved this printer from going into the trash. I am glad i stumbled across this program and the website. (used on Epson Artisan 800).

  Tried other sites, but they did not work. This one worked like a charm, wish I had found this one first.

  It works. Phew! If only I'd found this website earlier.

  This program is a definate must have if you want to service your own printer. Using this program along with the servive manual (440,640,740) will help you to determine what the problem is. The program shows print head voltages, waste ink counter and reset, and recover print head functions just to name a few of the useful functions that this program has to offer. It returned my printer from a paperweight into a working Epson 640 in minutes. Even if your printer is working properly you can use this program ensure it will keep working. For less than $6.00 it is worth having.

  Printer reset with key then failed waste counter back to 100% after test print. Key no longer works!

2Manuals reply:
There is bug in Epson Photo 1390, 14000, 1410 firmware that put waste counter overflow back again after reset. This problem can be solved by updating printers firmware. Here is step by step manual how to fix it - www.2manuals.com/1400fw_update.php
