Abstract

A recording device includes: a transport unit configured to transport a medium in a plurality of transport speed modes; a driving unit configured to drive the transport unit with a plurality of speed profiles, each corresponding to one of the plurality of transport speed modes; a current sensor configured to measure a reference current the driving unit, the reference current being a current flowing in the driving unit when the medium is transported in a loosened state; and a control configured to acquire a plurality of current profiles, each corresponding to one of the speed profiles, based on the reference current. The control unit is configured to acquire a first current profile based on the reference current when the medium is transported in a first transport speed mode, and to generate a second current profile based on the first current profile.
