Abstract
A recording head has a plurality of nozzles adapted to eject ink droplets toward a printing medium which is transported in a first direction. A head supporting member supports the recording head. A light emitter is operable to emit light. A light receiver is adapted to receive light reflected from the printing medium. The nozzles are arranged in the first direction to form a nozzle array. The light emitter and the light receiver are disposed between a first one of the nozzles and an upstream end of the head supporting member relative to the first direction. The first one of the nozzles is located in an upstream end of the nozzle array relative to the first direction. The light emitter and the light receiver are provided on the head supporting member and arranged in a second direction perpendicular to the first direction.
