Theory of Operation

Ink loader

The ink loader consists of four parallel channels with an ink melting element at
the end of each of the four channels. Ink sticks, one color loaded in each channel,
are pressed by coil-spring pressure into the melting elements. As ink is required
by the printhead, the appropriate color's melting element is activated and the
end of the ink stick is melted. The melted ink drips into the ink reservoirs of the
printhead underneath. Sensors in the ink loader alert the customer to install
more ink sticks before the current sticks are completely consumed.
