摘要： 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.

摘要： In a thermal head control method for thermally making a stencil master plate from a thermal stencil master plate sheet in the manner of a dot matrix for each line and forming an independent hole for each dot, a physical quantity representing the temperature of the thermal head, such as a time interval Ti for the plate making action by the thermal head for each line and a temperature actually measured from the thermal head, is measured before the plate making action of the next line. The measured temperature is compared with a prescribed value, and if the temperature is lower than the prescribed value, the thermal head is driven (pre-heated) at a power level which is lower than the rated power output and would not affect the thermal stencil master plate sheet. The effective heat emitting property of the thermal head is made uniform without regards to other factors, and a satisfactory perforation is carried out on a thermal stencil master plate sheet at all times.

摘要： A method of cleaning a media preheater that is positioned in the media path of a printer is disclosed. The media preheater has a fixed heater and a movable plate array biased toward the heater such that printer media passing between the plate array and the heater is compressed therebetween and heated. The preheater may be positioned upstream of a print head and downstream of a media advancing mechanism in the media path. More than one plate may be provided in the plate array to accommodate non-planarity of the heater or the printing media. The method elevates the temperature of the contact surface of the preheater to a cleaning temperature that is greater than the operating temperature and then passes a chase sheet over the surface to remove contamination from the preheater surface.

摘要： A method for controlling the energization of a thermal printing heating element by a succession of current impulses (I) separated according to a printing raster is described. The current impulses (I) upon exceeding a pre-given energy content effect a printing event and in the case of falling below this energy content effect a preheating. At each raster time point (t1) the printing requirement is ascertained for a predetermined number of yet to follow raster time points (t2, t3) and for raster time points (t2, t1) without printing requirements and lying in advance of a raster time point (t3) with a printing requirement the current impulses (I1, I2) are progressively increased. Through the use of this method a thermal printer with a high printing speed is achieved.

摘要： A recording apparatus uses a thermal head which includes a plurality of heat generating elements divided into blocks. Recording is controlled by sequentially selecting each block during a recording period and driving the heat generating elements in that block according to recording data. Preheating is controlled by simultaneously selecting all blocks during a preheat cycle and driving all of the heat generating elements according to preheat data. The energy used in preheating is insufficient to cause recording.
