Abstract
In an embodiment, a fluid ejection device includes a die substrate with a chiclet adhered by its front side to the die substrate. The fluid ejection device also includes an ink delivery slot formed through the chiclet from its back side to its front side. The fluid ejection device further includes a mixing bead at the back side of the chiclet, adjacent the ink delivery slot.
Claims15
A fluid ejection device comprising:
- a die substrate;
- a chiclet adhered by a front side thereof to the die substrate;
- an ink delivery slot formed through the chiclet from a back side thereof to the front side thereof;
- a mixing bead at the back side of the chiclet, adjacent the ink delivery slot;
- and
- at least one electromagnet on at least one side of the ink delivery slot to raster the mixing bead back and forth across the ink delivery slot away from and toward the at least one side.
A processor-readable medium storing code representing instructions that when executed by a processor cause the processor to:
- turn on first and second electromagnets in a fluid ejection device to raster a mixing bead back and forth across an ink delivery slot away from and toward the first and second electromagnets;
- wherein the first electromagnet is located at a first side of the ink delivery slot and the second electromagnet is located at a second side of the ink delivery slot.
A processor-readable medium storing code representing instructions that when executed by a processor cause the processor to:
- turn on a single electromagnet located at a first side of an ink delivery slot in a fluid ejection device, such that the single electromagnet has a first polarity;
- and
- turn on the single electromagnet such that the single electromagnet has a reverse polarity,
- wherein turning on the single electromagnet to have the first polarity and turning on the single electromagnet to have the reverse polarity is to raster a mixing bead back and forth across the ink delivery slot away from and toward the single electromagnet.
