Once inserted, the ink stick is advanced by the belt drive approximately 50 mm. Stock Keeping
Unit (SKU) sensors in the ink loader check features on the bottom of the ink stick and deter-
mine which type of ink is present. One sensor is employed for the CMY sticks, distinguishing
between the NA/EU sold sticks and the other 2 SKU's. The black ink loader chute employs 2
SKU sensors which can distinguish all three SKU families.
Principles of Operation
If the SKU sensors detect the correct ink stick, then the belts continue to advance the ink into
the ink loader, allowing additional sticks to be inserted. If the SKU sensors detect an incorrect
ink stick, a user interface message requests that the user remove the stick and a software
counter is updated to record that an incorrect ink stick was inserted. It is possible for the user to
force the ink stick forward into the ink loader rather than removing the ink stick as requested. If
this happens, the printer will continue to operate.
