Theory of Operation
Ink loader
The ink loader allows the printer to automatically load ink sticks into the
printhead as they are required to correct an ink low condition.
When an ink-low condition is noted, the following sequence takes place:
■
The printhead shuttles left to the ink load position.
■
The printhead door motor energizes to open the printhead door.
■
The ink feed motor for the appropriate ink stick energizes to drive a
belt featuring paddles that push one ink stick down into the
printhead.
■
The ink drop sensor detects when an ink stick is pushed into the
waiting printhead.
■
The four origin sensors detect the position of each of the ink load belts
so the paddles of each belt will be in the proper position to push the
next ink stick into the printhead.
