  If you've replaced the heads, or removed/re-installed them, you need this! Also does a power nozzle clean - worth the money just for that. Note it needs DOS or a DOS box in Windows.

  Just wanted to write and THANK YOU for making such GREAT products.

I just reset my Epson 1430 printer. I\'m using it with bulk pigmented ink...and a custom color profile. I love it...and thanks to you I\'ll be able to get several more years out of it.
Best regards.Tomas Jomad
