What Is A Low Ink Warning?
The Low Ink Warning is the ink counter calculating the remaining level of ink and advising you
that the FINE Cartridges are running out of ink during printing.
The ink counter assumes the ink is full when a new FINE Cartridge is installed, and then starts
the remaining level of ink. In this instance, if an old FINE Cartridge is installed, a message that
the remaining level of ink cannot be detected appears.
Note
When the "!" mark appears on the Low Ink Warning
The ink level of the FINE Cartridge showing the "!" mark is low. You should ensure you have a
new FINE Cartridge.
