Abstract: A recording apparatus is provided with a transport roller pair which transports a medium toward a recorder, a feed roller which transports the medium toward the transport roller pair, and a controller which controls the transport roller pair and the feed roller. The controller is capable of executing a combined skew rectification mode which executes one of a first skew rectification operation in which a leading end of the medium abuts the transport roller pair using backward rotation of the transport roller pair and forward rotation of the feed roller and a second skew rectification operation in which the transport roller pair to rotate backward without driving the feed roller and discharges the leading end of the medium to the upstream side of the transport roller pair, and subsequently executes the other of the skew rectification operations.
