Epson Tylus CX4600 ink light

If any ink cartridge is empty, you won't be able to print until you replace the empty cartridge. Leave any empty cartridge installed in the device until you have obtained a replacement.

The print heads will clog up in a week or two. So you also won't be able to print until you clean the print heads.

This is a utility to manage your ink. Gives an accurate count of how many ink shots are left in each cartridge. The printer told me I need a new magenta but this program says I have 13% left. It also has separate routines for cleaning the black and color (unfortunately not individual cartridges)
