Why doesn't the Epson Status Monitor show the how much ink is left in the ink cartridges?

• The Status Monitor only works with a direct bi-directional connection and therefore will not work on a networked printer. If your printer is not networked, follow the directions below to install your Status Monitor.
  
  1. Restart your computer and close down any background applications by following the following directions:
  a) Press "CTRL+ALT+DEL". This will open the "CLOSE PROGRAM" window.
  b) One by one select "End Task" for all items EXCEPT the "EXPLORER" and "SYSTRAY".
  Note: The 'Close Program' window will close each time you click 'End Task' so you will need to press CTRL+ALT+DEL again after each 'End Task'. If you press CTRL+ALT+DEL twice in a row, your PC will reboot and you will have to start over again.
  2. Insert your Epson CD into your CD ROM drive, and double click on the MY COMPUTER icon.
  3. Double click on the Epson CD ROM drive, and then double click on the DRIVERS folder.
  4. Double click on the STM3 folder.
  5. Double click on the STMSETUP icon.
  6. Follow the prompts to complete the installation.
