摘要： An ink jet printer includes a distance adjust mechanism for adjusting in two steps a distance between a liquid nozzle-formed face of a print unit and the recording surface, and a unit having first and second cleaning members with different free end positions, lengths and/or thicknesses are arranged movable relative to the face and adapted to wipe a substance adhering to the face off of the face with a predetermined engagement condition. The substance is wiped off of the face by the first and second cleaning members having different engagement conditions when the face is a first distance from a recording surface, and is wiped off with the engagement condition of a wipe portion of the first cleaning member virtually equal to the engagement condition of a wipe portion of the second cleaning member associated with the first distance when the face is a second distance from the medium. Further, a height difference between the cleaning members is set almost equal to the distance the face is moved by the distance adjust mechanism.

摘要： Multi-valued image data corresponding to a pixel area is divided into the first scanning multi-valued data, first and second scanning common multi-valued data, and second scanning multi-valued data. A quantization processing is executed on each of the multi-valued data to generate first scanning quantized data, first and second scanning common quantized data, and second scanning quantized data. After that, these pieces of quantized data are combined for each scanning to generate first scanning combined quantized data and second scanning combined quantized data. According to this, the amount of pixels where dots are both recorded by performing a scanning by plural times (the amount of overlapping dots) is controlled, and while suppressing the image density variations, the granularity is held to a low level.

摘要： In a printing apparatus improvement of drying ability and reduction of consumed power are concurrently achieved by improving the efficiency of drying ink. More concretely, hot air is blown onto a print medium printed by ink, and a portion of the blown hot air is recovered and blown again. Before the hot air is blown, the print medium is heated by a preheating unit, making it higher than the dew point temperature of the blown hot air.

摘要： Provided is a temperature detection method capable of more accurately acquiring an environmental temperature and more accurately correcting temperature detection of a printhead. In a printing apparatus to which this method is applied, a previous printing time when the printhead has performed a printing operation is stored in a nonvolatile memory. The current time is acquired using a timer which always performs a time counting operation by power supply from an auxiliary power supply capable of supplying power independently of a main power supply that supplies power for performing the printing operation by the printing apparatus. A time elapsed after the previous printing time is calculated on the basis of the current time and previous printing time. The elapsed time and a predetermined time are compared. The temperature is measured using a sensor arranged in at least one of the printing apparatus and the printhead in accordance with the comparison result. A temperature is updated on the basis of the measured temperature.

摘要： A contamination of a printing medium caused by ink mist or the like is suppressed, which may scatter or float in an apparatus when margin-less printing is carried out in an ink jet printer. When margin-less printing for an edge of a printing medium P is performed, a predetermined edge area {circle around (1)} is printed using a smaller number of ejection openings during one scanning operation than that used for other areas {circle around (2)} and {circle around (3)}, while taking transportation errors relating to this end into consideration. This reduces the amount of ink mist resulting from ink ejected out of the edge of the printing medium during one scanning operation.

摘要： When recording a gradation pixel by performing pseudo-halftone processing, the occurrence of unevenness in the density in the recorded image is suppressed. For that purpose, when recording a pseudo-halftone image using dot patterns, a dot-pattern table storing a plurality of different dot patterns is provided for each gradation value. One dot-pattern table is selected from N dot-pattern tables based on gradation-value information for each pixel. One dot pattern is selected from the selected dot-pattern table, based on position information indicated by the pixel, and recording is performed using the selected dot pattern. It is thereby possible to prevent the concentrated use of a particular nozzle of a recording head, and suppress the occurrence of unevenness in the density due to characteristics of the specific nozzle.

摘要： By using an ink jet head, which has for each color two parallel columns of nozzles arranged side by side in the main scan direction and shifted from each other by one-half the pitch at which the nozzles are arranged in each column, odd-numbered rasters and even-numbered rasters making up an image are printed by the two nozzle columns. The registration between the odd- and even-numbered rasters is secured during the printing to produce an image with high print quality. For that purpose, the ink ejection timing between the two raster groups is shifted by a predetermined interval to form a plurality of adjustment patterns; the adjustment patterns printed are checked and, according to the check result, an adjustment value for the ink ejection timing between the two ink nozzle columns is entered; and the entered adjustment value is stored to be reflected on the actual printing operation. To facilitate the adjustment pattern check, the plurality of adjustment patterns have a dot distribution with a blue noise characteristic at a resolution at which the printing apparatus can print.
