Ink Loader - Xerox Phaser 8400 Service Manual

Ink Loader

The ink loader consists of four parallel channels with an ink melting element at the
end of each channel. 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.
