摘要： Provided is an image forming method which prevents the temperatures of printing heads from exceeding a predetermined temperature. In this image forming method, its basic assignment is changed when any one of the temperatures detected by the respective temperature sensors (61 to 64) exceeds the predetermined temperature (for example, 60°C). Specifically, each time the forming of an image on a printing medium (for example, a label) is completed, the temperatures of the respective printing heads (K1 to K4) are detected with the respective temperature sensors. When any one of the temperatures thus detected exceeds 60°C, the association of raster line regions with ink ejection opening arrays (N1 to N4) (the association of rasters with the printing heads) under the basic assignment is shifted one-by-one.

摘要： An inkjet printer (10) uses a printhead (12) that passes repeatedly across a print medium in individual swaths. The printhead (12) has individual nozzles (21) that are fired repeatedly during each printhead swath to apply an ink pattern to the print medium. Before any given swath, the printer (10) analyzes factors that might require a reduction in print density. Anticipated printhead temperature is one factor that might require a reduction in print density. The printer (10) monitors the print density and peak printhead temperature during each printhead swath. It then uses these values to calculate, prior to each new swath, a maximum permissible print density. If a reduction in print density is required, the printer (10) temporarily disables selected nozzles (21) to produce a reduced-height swath rather than pausing between swaths or reducing the printhead velocity relative to the page.

摘要： In an ink jet printhead (100) comprising ejection resistors (Ri) and MOS transistors (TRi) for supplying the resistors the energy for ejecting droplets of ink, integrated on the same semiconductor substrate, a given range of values is defined for the ratio of the channel resistance (Rc) during conduction of the MOS transistor to the resistance (R) of the ejection resistor so that the energetic operating point (El) of the ejection resistor is automatically compensated for variations in temperature (Ts) of the substrate, thereby assuring quality of printing and preventing ejection resistor conditions of operation liable to damage the resistor itself.

摘要： A color ink-jet printer (50) having a heating blower system for evaporating ink carriers from the print medium after ink-jet printing. A preheat drive roller (62) engages the medium and draws it to a print zone (56). The drive roller is heated and preheats the medium before it reaches the print zone. At the print zone, a print heater (72) heats the underside of the medium via radiant and convective heat transfer through an opening pattern formed in a print zone heater screen (66). The amount of heat energy is variable, depending on the type of the print medium. A crossflow fan (90) at the exit side of the print zone (56) directs an airflow at the print zone in order to cause turbulence at the medium surface being printed and further accelerate evaporation of the ink carriers from the medium. An exhaust fan (82) and duct system (80) exhausts air and ink carrier vapor away from the print zone and out of the printer housing.
