Abstract: In some examples, a printhead drop detector comprises a plurality of drop detection units. Each drop detection unit may comprise a radiation source and radiation detector and may be to detect a drop passing through a sampling volume between the radiation source and the radiation detector. A radiation detector of a first drop detection unit and a radiation source of a second drop detection unit is arranged on a first side of the sampling volume; and a radiation source of the first drop detection unit and a radiation detector of the second drop detection unit is arranged on the second side of the sampling volume.

Abstract: In one example in accordance with the present disclosure a drop detection device is described. The device includes an emitter member having a number of emitter cavities to relay a number of beams towards a number of detector cavities in a detector member. The device also includes a detector member that is spaced from the emitter member. The detector member includes a number of detector cavities to receive a number of beams from the number of emitter cavities. The device also includes a number of ribs coupled to both the emitter member and the detector member. The number of ribs space and align the emitter member and detector member and align the number of emitter cavities with the corresponding number of detector cavities.

Abstract: Apparatus is described that has a flexion component configured to apply a force to a first portion of media within a media path of a media processing device. The apparatus has a support portion configured to couple the apparatus to the media processing device. The media path provides a path along which the media is transported and has a feed area. The flexion moves a second portion of the media away from the feed area of the media path. A method of applying a force to media is also described.
Abstract translation: 描述了具有被配置为向介质处理设备的介质路径内的介质的第一部分施加力的屈曲部件的装置。 该装置具有配置成将该装置耦合到该媒体处理装置的支撑部分。 媒体路径提供了传送媒体的路径，并具有馈送区域。 弯曲使媒体的第二部分远离媒体路径的馈送区域。 还描述了向介质施加力的方法。

Abstract: Apparatus to detect droplets and methods for detecting droplets are described. The apparatus comprise a light emitter and a light detector. The light emitter is to emit light along an optical axis, the light having a spatial intensity distribution profile with a peak that is non-coincident with the optical axis. The light detector is located relative to the light emitter such that, in use, the peak of the spatial intensity distribution profile is incident on the light detector.

Abstract: In some examples, a printhead drop detector comprises a plurality of drop detection units to detect any drops passing through a sampling volume between the radiation source and the radiation detector. A radiation detector of a first drop detection unit and a radiation source of a second drop detection unit is arranged on a first side of the sampling volume and a radiation source of the first drop detection unit and a radiation detector of the second drop detection unit is arranged on the second side of the sampling volume. The distance between the first drop detection unit and the second drop detection unit is based on an angle of a beam producible by the first radiation source such that the beam is wide enough to cross into a portion of the sampling volume corresponding with the second drop detection unit.
