  • Patent number: 5485286
    Abstract: An image communication apparatus, for recording an image using a recording head for ejecting an ink from an ejection port by utilizing energy generated by an ejection energy generation element, includes a communication section for communication a procedure signal associated with a communication and image data, a driving section for driving the recording head in accordance with the image data received by the communication section, a preservation section for performing preservation processing of the recording head, and a control section for discriminating a procedure signal transmitted after the image data, and controlling an operation of the preservation section on the basis of the discrimination result. When the control section discriminates that a specific procedure signal for successively performing reception is transmitted, it causes the preservation section to execute the preservation processing.
