Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
An image communicating apparatus comprising: communication means for communicating with a transmitting apparatus to send and receive procedure signals associated with communication of image data, wherein said communication means to a reception mode upon receiving a procedure signal indicating a presence of an original sheet to be transmitted from a partner station after calling the partner station; recording means for ejecting an ink droplet onto a recording member to record an image in accordance with the image data received by said communication means; recovery means for performing a predetermined recovery operation of said recording means to maintain image quality; and control means for causing said recovery means to execute the predetermined recovery operation in accordance with a specific procedure signal transmitted to or receiving from the partner station before receiving image data, when said communication means shifts to the reception mode after the calling of the partner station.
Claim 2
Dependent Claim
148 words
An image communicating apparatus comprising: communication means for communicating with a transmitting apparatus to send and receive procedure signals associated with communication of image data, wherein said communication means to a reception mode upon receiving a procedure signal indicating a presence of an original sheet to be transmitted from a partner station after calling the partner station; recording means for ejecting an ink droplet onto a recording member to record an image in accordance with the image data received by said communication means; recovery means for performing a predetermined recovery operation of said recording means to maintain image quality; and control means for causing said recovery means to execute the predetermined recovery operation in accordance with a specific procedure signal transmitted to or receiving from the partner station before receiving image data, when said communication means shifts to the reception mode after the calling of the partner station.
Claim 3
Dependent Claim
162 words
An image communicating apparatus comprising: communication means for communicating with a transmitting apparatus to send and receive procedure signals associated with communication of image data, wherein said communication means assumes a receiving mode for accepting transmitted image data, and sends a transmitted procedure signal to the transmitting apparatus indicating that said communicating means is in the receiving mode, when the image communicating apparatus receives a procedure signal from the transmitting apparatus indicating a presence at the transmitting apparatus of image data to be sent; recording means for ejecting an ink droplet onto a recording member to record an image in accordance with the image data received by said communication means; recovery means for performing a predetermined recovery operation of said recording means to maintain image quality; and control means for initiating operation of said recovery means in response to the transmitted procedure signal; wherein said control means initiates operation of said recovery means in synchronism with transmission of the transmitted procedure signal.
Claim 4
Dependent Claim
162 words
An image communicating apparatus comprising: communication means for communicating with a transmitting apparatus to send and receive procedure signals associated with communication of image data, wherein said communication means assumes a receiving mode for accepting transmitted image data, and sends a transmitted procedure signal to the transmitting apparatus indicating that said communicating means is in the receiving mode, when the image communicating apparatus receives a procedure signal from the transmitting apparatus indicating a presence at the transmitting apparatus of image data to be sent; recording means for ejecting an ink droplet onto a recording member to record an image in accordance with the image data received by said communication means; recovery means for performing a predetermined recovery operation of said recording means to maintain image quality; and control means for initiating operation of said recovery means in response to the transmitted procedure signal; wherein said control means initiates operation of said recovery means in synchronism with transmission of the transmitted procedure signal.
Claim 5
Dependent Claim
21 words
An apparatus according to claim 1 or 2, wherein the transmitted procedure signal instructs the transmitting apparatus to transmit image data.
Claim 6
Dependent Claim
39 words
An apparatus according to claim 1 or 2, wherein said control means causes said communication means to transmit to the transmitting apparatus a procedure signal indicating an image data a reception standby operation after the recovery operation is completed.
Claim 7
Dependent Claim
21 words
An apparatus according to claim 1, wherein said recovery means performs a recovery operation that supplies ink to said recording means.
Claim 8
Dependent Claim
29 words
An apparatus according to claim 1, wherein said recovery means performs a recovery operation tat causes said recording means to perform an idle ejection operation not intended for recording.
Claim 9
Dependent Claim
32 words
An apparatus according to claim 1 or 2, wherein said recording means has nozzles of one line corresponding to a maximum width of a recording member which can be used in recording.
Claim 10
Independent Claim
60 words
An apparatus according to any one of claims 1, 2, 5 and 6, wherein said recording means comprises a plurality of nozzles and a plurality of electro-thermal conversion elements arranged in correspondence with the nozzles, said electro-thermal conversion elements being driven according to the image data to generate bubbles by heat generated by said electrothermal conversion elements, thereby ejecting ink.
