A first region is defined on the head face so as to include a first group of nozzles among all nozzles formed with a recording head. A first amount is defined as a difference between a first reference position at which a leading edge of a recording medium situated at a recording start position is placed and a first shifted position at which the leading edge of the recording medium, which has been most shifted in a subscanning directions and most inclined within a feeding tolerance of a feeder, is placed. A first virtual leading edge is defined at a position where is shifted from the first reference position to a downstream side of the subscanning directions by the first amount. A second virtual leading edge at a position where is shifted from the first reference position to an upstream side of the subscanning directions by the first amount. A first type of recording is performed with the first group of nozzles, when an end of the first region in the upstream side of the first directions is situated at the first virtual leading edge. A second type of recording is performed with all the nozzles, when the end of the first region in the upstream side of the first directions is situated at the second virtual leading edge.

Recording method and recording apparatus

Recording paper fed from a paper feed section comes in contact with a paper detection member of a detector unit and the paper detection member is rotated about a first fulcrum, shading the optical axis of an optical sensor. When the recording paper passes through and the paper detection member is brought out of contact with the recording paper, the paper detection member is restored to the former position and does not shade the optical axis. A carriage/cartridge detection member of the detector unit comes in contact with a carriage engagement part and a cartridge engagement part placed in a carriage and is rotated about a second fulcrum, shading the optical axis of the optical sensor. When the carriage/cartridge detection member is brought out of contact with the engagement parts, the carriage/cartridge detection member is restored to the former position and does not shade the optical axis.
