MacDoug,
This is how I think checking ink levels is done on your machine-
1. Do a search/find on Epson Printer Utility.
2. Double click that.
3. A printer list will now appear.
4. Select and double click (the name of) your printer
5. A new window will appear with several options. The top-most indicates ink level. Click that.
Note: With Epson printers this is a calculated level (rather than a measured level) based on the number of pages printed since the ink cartridges were replaced.
