Ink Loader
The ink loader consists of four parallel channels with an ink melting
element at the end of each of the four channels. (Refer to Figure 1-23.)
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.
If the ink level sensors inside the printhead detect that the printhead
has run out of ink, but the ink low/out sensors are not activated, the
front panel reports an “Ink Jam” error.
