  • Publication number: 20240100826
    Abstract: A power supply control apparatus comprises a first power supply supplying power to a controller and a second power supply supplying power to an operation unit and a power controller. The operation unit receives an operation for switching the first power supply on and off. The power controller is operable to turn on the first power supply according to the signal from a timer or the operation by the operation unit, and to turn off the first power supply according to a state of the controller. The controller, upon at least either of the operation by the operation unit or the signal from the timer, performs a setting to the timer of a time at which to turn on the power from the first power supply or a time at which to turn off the power from the first power supply.

  • Patent number: 10740056
    Abstract: A printing apparatus conveys a printing medium in a first direction, and includes an encoder that outputs a predetermined signal in accordance with a conveyance amount of the printing medium in the first direction, and a print head having a plurality of nozzle rows, each of which includes a plurality of nozzles ejecting ink, arrayed in a second direction intersecting with the first direction. In addition, a print engine is connected with the print head and performs conversion processing from image data into print data. The print engine has a first buffer storing the image data, has a second buffer storing the print data, and converts image data stored in the first buffer into print data in response to a first interrupt signal based on the predetermined signal output from the encoder, and stores the print data in the second buffer.

  • Patent number: 10730290
    Abstract: A recording apparatus performs converting each of recording data and control data for controlling a recording head into transfer data in a command format and transmitting the transfer data to the recording head via a transmission path, and detecting, in the recording head, an error in the received transfer data, and, in the transmission after detecting the error, reconstructs next transfer data in such a manner that a command that has been included in the transfer data in which the error has occurred among commands concerning the control data and that is scheduled not to be included in the next transfer data is included in the next transfer data, and then transmits the next transfer data reconstructed.

  • Patent number: 9427997
    Abstract: There is provided a data processing apparatus, a printing apparatus and a data processing method, that can reduce a processing load and a processing time in reading data even in a case where null data is added to print data for correcting displacement of a printing position caused by inclination of a print head. To achieve this, there is provided a data processing apparatus including a first writing unit, a second writing unit and a reading unit. The reading unit reads out data arrays corresponding to the print target image and does not read out data arrays corresponding to outside of the print target image in the first storage unit, from a plurality data arrays stored in the second storage unit that have been written in by the second written in unit.

  • Patent number: 8882220
    Abstract: An encoder sensor is mounted on a printhead and optically reads an encoder film. And a number of pulses of a pulse signal proportional to a moving amount of a printhead is counted and stored as a count value in a memory within multiple ICs. The count value stored in the memories is reset while the pulse signal outputted from the encoder sensor is blocked by a gate or while a region other than near a boundary between a penetration region and a non-penetration region of the encoder film is being read.

  • Publication number: 20130027748
    Abstract: In an image processing apparatus which reads out image data for each unit region from stored image data in a scanning direction in printing and sequentially performs image processing, image data before image processing in a unit region preceding a unit region to undergo image processing is stored by a predetermined width from the first boundary between the preceding unit region and the unit region to undergo image processing. Image processing is performed by referring to the image data before image processing by the predetermined width from the first boundary, and image data before image processing in a unit region succeeding the unit region to undergo image processing by a predetermined width from the second boundary between the unit region to undergo image processing and the succeeding unit region.
