摘要： A color image recording apparatus operates in a color print mode and in a monochrome printing mode. A set of color print heads are driven in accordance with corresponding color image data. A monochrome print head is driven in accordance with black image data. A controller transmits in parallel or in serial the color image data and the black image data to the corresponding print heads in a color printing mode. The controller transmits the black image data faster in the monochrome printing mode than in the color printing mode, thereby increasing printing speed. The controller may include signal processing circuits such as compressing circuits and expanding circuit for the respective color image data and black image data. In the monochrome printing mode, the controller divides the black image data into a plurality of segments and supplies the segments in parallel to the signal processing circuits. The signal processing circuits process the segments and supply the processed data to the monochrome print head in a predetermined sequence, thereby increasing printing speed.

摘要： A printer receives a bit-mapped image signal representing an arbitrary bit-mapped image, and generates an independent pattern signal having a certain dot density, representing a shade of gray. The printer discriminates between edge dots and interior dots in the bit-mapped image signal, and generates a corresponding discrimination signal. A logic circuit outputs edge dots that are present in the bit-mapped image signal, and interior dots that are present simultaneously in the bit-mapped image signal and pattern signal. The dots output by the logic circuit are printed to produce outlines filled with a shade of gray.

摘要： A toner image fixing device in an electrophotographic image forming apparatus has a heating roller containing a heater and a backup roller, a surface of which is in contact with a surface of the heating roller. A toner image on the paper is fixed by causing the paper to pass through a contacting portion of the heating roller and the backup roller. The toner image fixing device also has a driving device for supplying driving power to the heating roller or the backup roller to rotate both the heating roller and the backup roller, and a controller. The controller controls the driving section in such a way that both the heating roller and the backup roller begin to rotate intermittently immediately after an electric power supply switch of the apparatus is turned on and heat generation from the heater is initiated, and subsequently begin to rotate continuously when the backup roller achieves one revolution by the intermittent rotation. Alternatively, the rotation speed of the heating roller and backup roller is gradually and continuously increased immediately after electric power is initiated and subsequently reach a constant speed.

摘要： Bit data of a received video signal is partially converted into a first signal representing a data sequence corresponding to the resolution of an LED head. The first signal is transmitted to the LED head in the form of a real printing data signal that is to be printed on a basic raster line in synchronism with a line timing signal. The remaining bit data of the received video signal, which are not converted into the first signal, are converted into a second signal representing another data sequence, and then stored in a line buffer. The second signal stored in the line buffer is transmitted to the LED head in the form of a real printing data signal that is to be printed on an additional raster line in synchronism with an additional line timing signal. The LED head drive energy with which the basic raster lines are printed and another LED head drive energy with which the additional raster lines are printed are set independently of each other. The LED head may be provided with such a resolution function.

摘要： A non-impact printer include a print head with a plurality of print elements such as light emitting diodes (LEDs). A driver drives the plurality of LEDs in accordance with logical states of corresponding bits of print data. A non-volatile memory stores energy specifying data. The energy specifying data describes an amount of drive energy that should be supplied to each of the plurality of print elements when each of the plurality of LEDs are driven during the printing. A random number generator generates random numbers. An adder adds the random numbers to the values of the energy specifying data to produce the energy specifying data that fluctuates within a predetermined range. Each of the plurality of LEDs is supplied with an amount of drive energy to in accordance with the fluctuating energy specifying data, thereby rendering the variations in print density of an entire image not detectable.

摘要： A printing head drive circuit of a printer is mounted on the side of a carriage having a printing head attached thereto for a allowing said carriage to act as a heat sink. Hereby, no particular cooling means (heat sink, cooling fan and the like) is required for printing head drive elements. In addition, a controller and heat generating parts can be completely separated. Thus, it can be anticipated to reduce the number of parts and the cost required for assembling the whole structure as well as to improve reliability of the printing head drive circuit.
