Abstract
A recording apparatus includes a recording unit for ejecting an ink to a recording member, a detection unit for detecting a remaining amount of ink, a memory for storing receiving data, and a control unit for controlling an operation of the recording unit to record an image in accordance with the receiving data, and controlling the memory to store image data in the memory. The control unit controls the memory in accordance with an output from the detection unit upon completion of recording of a predetermined volume of data, clears data stored in the memory when the output from the detection unit indicates a presence of ink, and preserves data stored in the memory when the output from the detection unit indicates an absence of ink.
Claims12
A recording apparatus comprising:
- recording means for ejecting ink onto a recording member;
- detection means for detecting a remaining amount of ink;
- storage means for storing received data, said storage means being capable of storing at least a page of data;
- and
- control means for controlling an operation of said recording means to record an image in accordance with the received data, and controlling said storage means to store image data in said storage means,
- wherein said control means controls said storage means in accordance with an output from said detection means upon completion of recording of a current page of data and before initiation of recording of a next page of data, and wherein said control means clears the current page of data which has been stored in said storage means when an output from said detection means indicates a presence of ink, and preserves the current page of data which has been stored in said storage means when the output from said detection means indicates an absence of ink.
A recording apparatus for recording a received image on a recording material using recording means for ejecting ink in accordance with image data, comprising:
- detection means for detecting a remaining amount of ink after completion of recording of a current page of data and before initiation of recording of a next page of data;
- storage means for storing received data, said storage means being capable of storing at least a page of data;
- and
- control means for controlling said storage means such that storage of the received data in said storage means is performed in parallel with recording of the received data by said recording means,
- wherein said control means controls said storage means in accordance with an output from said detection means, and wherein when said detection means detects an absence of ink after completion of recording of a current page of data and before initiation of recording of the next page of data, said control means preserves the received current page of data which has been stored in the storage means and preserves successive received data which is to be stored in said storage means.
