This can be fixed as follows:
- Connect the printer directly, i.e. via USB to the PC or laptop and turn the printer on
- Install "Status Monitor 3 1.1b" from the Epson website:
http://esupport.epson-europe.com/FileDetails.aspx?lng=en-GB&id=31761
The name of the downloaded file is: epson31761eu.exe
Note: there is no separate Windows 7 x64 version, so use the Windows Vista x64 version for that platform - Right-click the "Status monitor 3" icon in the tray and:
- Epson AL-C900 -> Printer Setting...
- Check "Continue printing when consumables are empy"
