Theory of Operation
The Ink Stick Gate Solenoid (one for each color) prevents movement of the ink stick until it is
sensed. When the correct ink stick is inserted, the Solenoid is activated to lower the gate. The
Configuration Sensor is activated to determine when the ink stick has traveled past the gate.
When the ink stick has moved sufficiently forward, the gate is returned to the Locked position.
The gate will also lower when an ink stick is moved back up to the gate to allow removal. When
you move an ink stick back, an ink stick back up the ink channel and contact the raised gate,
the SKU notch A (or notch E on Enterprise ink sticks) will be presented to the lower-most SKU
sensor. Notch A and E are always have material present (logical 1). The transition of the sen
-
sor from no material to material present signals the printer to lower the gate.

The Chute Level Sense detects the Ink Stick when the Ink Loader Door is closed and alert the
user to install more ink sticks before the current sticks are completely consumed. The Stock
Keeping Unit (SKU) Configuration Sensor detects the presence or absence of ink thereby
determining the ink SKU.
The Ink Level Sensors inside the Printhead detect that the Printhead has run out of ink.
