摘要： An inkjet recording apparatus in which displacements of dots are reduced. In the inkjet recording apparatus, recording data is read out from a recording buffer at a period corresponding to a second resolution. The apparatus determines whether or not to delay the timing at which the readout is performed by an interval corresponding to one-half of the period corresponding to a first resolution. The apparatus also selects whether to drive an inkjet head in a front half or a last half of the period corresponding to the first resolution.

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： A method of adjusting bidirectional registration to reduce negative effects on the image such as “banding” even if bidirectional registration includes a slight amount of displacement is provided. For that purpose, correction is applied to a first adjustment value for adjusting a bidirectional registration displacement in response to an extent of inclination of a printing head to obtain a second adjustment value. Then a bidirectional printing is performed with timing adjusted on the basis of the second adjustment value. As a result of that, even if there is a slight variation in an adjustment value of the bidirectional registration and the inclination of the printing head, the banding generated by this can be reduced as much as possible.

摘要： In an image printing apparatus for printing an image by combining dots of a plurality of sizes, a banding problem attributable to variations in conveying operation, and a temperature rise of a print head with an increase of the number of ejections are solved with a relatively simple configuration. To this end, a combination of dots of a plurality of sizes is assigned to each of pixels expressed at a plurality level of density. In this assignment, a dot larger than a pitch of an image resolution is preferentially allocated to a pixel having a density level higher than that to which one dot smaller than the pitch of the image resolution is allocated.

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： When a printing position is displaced by an inclination of a printing head, for example, the displacement can be corrected in an easy and effective manner and a user can easily recognize the displacement of the printing position to correct the displacement. To realize this, dots for forming a test pattern are formed by different scannings by a nozzle group including a plurality of nozzles positioned at one end side of a nozzle row and a nozzle group including a plurality of nozzles positioned at the other end side of the nozzle row. Depending on displacements of the printing positions of these dots, the plurality of nozzles constituting the nozzle row are divided into a plurality of divided nozzle groups. Then, the printing position is adjusted on the basis of the divided nozzle groups.
