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.
