ABSTRACT:
A liquid ejecting head is operable to eject liquid toward a target medium. A platen opposes to the liquid ejecting head, and has a first region formed with a plurality of projections. A first detector includes a light emitter operable to emit light toward the platen and a light receiver adapted to receive light reflected from the platen. The first detector is operable to generate a detection signal in accordance with an amount of the light received by the light receiver. A controller is operable to obtain the detection signal at a plurality of positions in the first region to determine a threshold value of the detection signal for detecting whether the target medium exists on the platen.
