摘要： For each energy value of a number of energy values, the energy value is applied to cause a fluid-ejection nozzle to eject a fluid drop. After the energy value has been applied to the fluid-ejection nozzle, a velocity of the fluid drop is determined using a light-scattering drop detector of the fluid-ejection device. A turn-on-energy (TOE) for the fluid-ejection nozzle is determined based on at least the velocities of the fluid drops determined after applying the energy values to the fluid-ejection nozzle.

摘要： A fluid ejection assembly includes a fluid slot, and a group of uniformly spaced drop generators, where each drop generator is individually coupled to the fluid slot through a first end of a drop generator channel and to a connection channel at a second end of the drop generator channel. The fluid ejection assembly includes a pump disposed within a pump channel located between two drop generator channels, and is configured to circulate fluid from the fluid slot, into the connection channel through the pump channel, and back to the fluid slot through the drop generator channels.

摘要： One aspect is an aerosol detection arrangement including a light source for projecting a light beam. The arrangement includes a light collector configured to collect light scattered off liquid drops in an aerosol that enter the light beam and processing the scattered light into an output signal. The arrangement includes a controller for receiving the output signal from the light collector and uses the output signal to determine a predicted number of main liquid drops ejected.

摘要： In one embodiment, a drop ejector assembly includes a printhead, a drop zone immediately downstream from the printhead, an array of optical fibers exposed to the drop zone such that light scattered off drops in the drop zone illuminates at least some of the optical fibers in the array, and a photo detector operatively connected to the array of optical fibers for converting light from the optical fibers into an electrical signal. In another embodiment, a drop detector includes a light source for illuminating drops passing through a drop zone and a light sensor for sensing light scattered off drops in the drop zone. The length of drop zone is 3 mm or less and the light sensor has a cross sectional dimension less than the length of the drop zone.
