Abstract
A printer according to an embodiment includes a conveying unit, a holding unit, a supporting unit, a second detecting unit, and a control unit. The conveying unit conveys paper. The holding unit includes a light emitting unit configured to radiate light and a first detecting unit configured to detect the light reflected on the paper. The supporting unit supports the holding unit to be movable in an orthogonal direction orthogonal to a conveying direction of the paper. The second detecting unit is disposed on an opposite side of the light emitting unit across a paper conveying path, on which the conveying unit conveys the paper, and detects the light radiated by the light emitting unit. The control unit determines, based on a detection result of the second detecting unit, whether the light emitting unit is present in a position opposed to the second detecting unit.
