Recording device and curl determination method

A recording device comprising:

• a transport section that transports a medium, which has four side edges, along a medium transport path;
• a recording section which performs recording on the medium by discharging liquid corresponding to a liquid volume based on discharge data to a recording region of the medium, which is transported by the transport section, and causing the liquid to adhere to the medium;
• a determination section that determines whether or not curls are generated in the medium by
• dividing the recording region of the medium into a plurality of regions, and setting a continuous region, in which the plurality of regions are continued, as a determination region, the plurality of regions including an end part region which is the closest region to a corner section, in which two side edges are connected, of the medium,
• calculating an average value of liquid volume ratios of the liquid, which is discharged from the recording section to the determination region based on the discharge data of the liquid which is discharged from the recording section to the medium, to a maximum liquid volume of the liquid which is configured to be discharged from the recording section, and
• determining whether or not the average value of the liquid volume ratios, which are calculated for the determination region, is larger than a predetermined threshold, and determining that curls are generated in the medium when determining that the average value is larger than the threshold;
• and
• a dryness degree adjustment section that, when the determination section determines that the curls are generated, performs adjustment such that the medium, which is transported along the medium transport path, is dried at a higher dryness degree than a case in which it is determined that the curl is not generated.
