Patent ID: 8287115

Claim:
A recording apparatus comprising: a recording unit that ejects liquid so that the liquid is recorded on a recording medium; a transporting unit that transports the recording medium; a plurality of microwave irradiation units that irradiate microwaves to the recording medium, the plurality of microwave irradiation units being positioned above the transporting unit at a position which is downstream from the recording unit in a transport direction; a plurality of microwave reception units that receive the microwaves reflected from the recording medium, each microwave reception unit corresponding to one of the plurality of microwave irradiation units; and a microwave irradiation control unit that determines a dryness level of a plurality of portions of the recording medium based on a reception level by the plurality of microwave reception units corresponding to the plurality of portions of the recording medium, calculating a reflectance incident to each microwave reception unit, comparing the calculated reflectance to a predetermined dryness level, calculating a necessary irradiation dose to achieve the predetermined dryness level based on the difference between the measured reflectance and the predetermined dryness level, and controlling an irradiation dose or an irradiation intensity of the microwaves irradiated by each of the microwave irradiation units by causing the microwave irradiation units to each irradiate the necessary irradiation dose toward the corresponding portion of the recording medium.
