    摘要: One aspect is a drop detection arrangement including a light source for projecting a light beam for scattering light off of an ejected drop. The arrangement includes a light collector configured to collect the scattered light off the ejected drop and a light detector coupled to the light collector and configured to process scattered light into an output signal. The arrangement includes a controller configured to receive the output signal from the light detector. The output signal is indicative of the condition of the ejected drop.

    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.

    摘要: An apparatus includes micro-electromechanical (MEM) devices, a charge source, and a discharge mechanism. Each MEM device has different states based on a charged induced thereon. The charge source is to induce the charge thereon such that the MEM devices each enter one of the different states thereof. The discharge mechanism for the MEM devices is to discharge the induced thereon. The discharge mechanism includes one of a resistor for each MEM device and an ultraviolet (UV) light source. The resistor is to discharge the charge on its MEM device to ground. The UV light source is to emit photons onto the MEM devices, such that the photons discharge the charge on the MEM devices via photoelectric effect.
