Abstract: A recording device, when recording is performed on a predetermined type target recording medium stored in a storage unit, drives a surface potential adjustment unit so that a surface potential is a positive potential within a predetermined range. By configuring such a recording device, it is possible to suppress adhesion of ink to an ejecting unit, and occurrence of an ink ejection failure can be suppressed.

Abstract: At step S115, a printer control unit refers to a table using an average print duty as an input, and determines a saturation temperature and a drum preliminary heating temperature. In this example, since the saturation temperature and the preliminary heating temperature with respect to the print duty are stored as a table, the printer control unit refers to the table using the average print duty as the input, and determines the saturation temperature and the drum preliminary heating temperature. At step S120, the printer control unit investigates a current drum temperature based on a measurement result of a temperature sensor. Subsequently, at step S125, the drum is heated or cooled until it reaches, of the saturation temperature and the drum preliminary heating temperature, the temperature for which the difference with the current drum temperature is smaller.

Abstract: A printer control unit controls a fan, based on an acquired reference temperature and an output of a sensor, to cause a temperature of a platen drum or a temperature of a sheet supported by the platen drum to be the reference temperature. Specifically, at step S100, the printer control unit acquires a type of the printing medium to be used for printing, acquires the reference temperature at step S110, and at step S150, controls an operating state of the fan, based on the temperature of the platen drum output by the sensor, such that the temperature of the platen drum becomes the reference temperature acquired at step S110. As a result, a temperature increase of the platen drum becomes substantially saturated at the targeted reference temperature.
