Abstract
A facsimile apparatus is equipped with an ink jet printing unit, capable of reducing the number of ink discharge recovery operations of the ink jet recording head, thereby reducing the ink consumption. The received image data are stored in an image memory, with inspection for errors in transmission in an error correction mode, and are collectively printed after a predetermined amount of image data are stored. The recording head is uncapped by a protocol signal transmitted after the image data.
Claims16
An image communicating apparatus comprising:
- communication means for effecting communication of a procedure signal relating to the communication of image data;
- memory means for storing the image data;
- communication control means for controlling said memory means so as to store therein image data transmitted from a transmitting unit;
- recording means for discharging ink toward a recording material in accordance with the image data stored in said memory means;
- capping means for capping said recording means, said capping means being capable of a capping operation wherein said capping means caps said recording means and a releasing operation wherein said capping means releases said recording means;
- first control means for controlling said capping means to release said recording means in response to storage in said memory means of a predetermined amount of image data and in response to an end of reception of a page of image data;
- and
- second control means for controlling said recording means so as to record the image data stored in said memory means after release of said recording means by said capping means.
