Description

METHOD FOR CHECKING RECEPTION STATE OF FAX SENDING JOB AT

SENDING SIDE

BACKGROUND

[0001] A facsimile is a device for sending images such as pictures, texts, diagrams, etc. to a desired place and receiving the same via communications lines. More specifically, a facsimile is a device that converts an unformatted image such as a picture, text, diagram, or the like into an electrical signal, transmits the electrical signal via a telecommunications network, reconstructs the electrical signal back to the original image and records the same.

[0002] Functions of a facsimile, a printer, a copier, and a scanner may be implemented in an integrated manner in a multi-function printer (MFP).

DETAILED DESCRIPTION OF EXAMPLES

[0023] Hereinafter, the present disclosure is described in detail with reference to the accompanying drawings, in which examples of the present disclosure are shown. The disclosure may be embodied in different forms and should not be construed as being limited to the examples set forth herein.

[0024] A "sending fax machine" refers to a device that decomposes images such as texts, diagrams, photographs, or the like into pixels, converts the pixels into electrical signals, and transmits the electrical signals to a receiving fax machine via a telecommunications network. The "receiving fax machine" refers to a device that reconstructs the electrical signals received from the sending fax machine back to the original image and records the same.

[0025] For example, a "fax machine" may be implemented with a facsimile, an image forming device, an image transmission device, an MFP, or the like. Some examples of the "image forming device" may include a device capable of performing an image forming operation, such as a printer, scanner, fax machine, MFP, display device, or the like. Some examples of the "image forming device" may also include a two- dimensional image forming device or a three-dimensional image forming device. [0026] In some examples, the "fax machine" may perform a fax transmission operation or a fax reception operation, using an Interet fax without establishing a telephone line dedicated to fax. For example, a fax machine may install a program used to perform a fax transmission operation or a fax reception operation. The fax machine may transmit a digital file through the program. In some examples, the fax machine may convert a paper document into a digital file through a scanner and transmit the digital file.

[0027] A user, in some examples, may use the fax machine to perform a fax transmission operation for a certain document. In such examples, the user may wait for the fax transmission operation to be completed or confirm a reception state from a menu capable of confirming a reception state for the fax transmission operation to confirm whether or not a receiving fax machine has received fax data for the certain document.

[0028] In some examples, to reduce waiting for the fax transmission operation to be completed, or to conform the reception state for the fax transmission operation from the menu capable of confirming the reception state for the fax transmission operation, the fax machine may receive response information on the reception state for the fax transmission operation, based on setting information in which a method of confirming the reception state for the fax transmission operation can be set.

[0029] FIG. 1 is a conceptual diagram illustrating a process in which a sending fax machine sends, to a receiving fax machine, fax data including setting information in which a method of confirming a reception state for a fax transmission operation can be set, and the receiving fax machine transmits, to the sending fax machine, response information of the reception state for the fax transmission operation, according to an example of the present disclosure.

[0030] Referring to FIG. 1, a sending fax machine 10-1 may send the fax data of a certain document to a receiving fax machine 10-2 based on the setting information in which the method of confirming the reception state for the fax transmission operation of the certain document can be set.

[0031] For example, the sending fax machine 10-1 may display a user interface 101 to set the method of confirming the reception state for the fax transmission operation of the certain document through a user interface unit 1130-1. In some examples, the user interface 101 may include an interface 102 to set a method of receiving the response information on the reception state for the fax transmission operation, and a type of the response information.

[0032] For example, an email method, a fax method, and the like may be included in the method of receiving the response information on the reception state for the fax transmission operation. In some examples, the type of the response information may include a response for giving a confirmation for the reception state for the fax transmission operation, and a signature response for giving, responsive to signing, a confirmation for the reception state for the fax transmission operation.

[0033] In some examples, the sending fax machine 10-1 may obtain image data corresponding to the certain document, and setting data corresponding to the setting information in which the method of confirming the reception state for the fax transmission operation can be set. The sending fax machine 10-1 may send, to the receiving fax machine 10-2, fax data 103 for the fax transmission operation including the image data and the setting data.

[0034] The receiving fax machine 10-2, in some instances, may receive the fax data 103 from the sending fax machine 10-1. The receiving fax machine 10-2 may obtain, from the fax data 103, the setting information in which a method of transmitting the response information on the reception state can be set. For example, the method of transmitting the response information may be set as a fax method, and the type of the response information may be set as the signature response.

[0035] In some examples, the receiving fax machine 10-2 may obtain the image data from the fax data 103 and reconstruct the image data back to the certain document. The receiving fax machine 10-2 may, in some instances, display a user interface 104 to receive confirmation of a reception state of the reconstructed certain document through a user interface unit 1130-2. For example, the user interface 104 may include a user interface 105 capable of receiving a recipient’s signature. The receiving fax machine 10-2 may receive the signature of the recipient. In some examples, when an input for the signature of the recipient is received, the receiving fax machine 10-2 may transmit, to the sending fax machine 10-1, response information 106 on the reception state for the fax transmission operation.

[0036] In some examples, the sending fax machine 10-1 may receive, from the receiving fax machine 10-2, the response information 106 on the reception state for the fax transmission operation. The response information 106 on the reception state for the fax transmission operation may include at least one of information on whether or not reception of the fax data is completed, information on a time at which the reception of the fax data is completed, information on whether or not the fax transmission operation is successful, and information on the signature of the recipient. The sending fax machine 10-1 may display the response information 106, in some examples. A user may confirm the reception state for the fax transmission operation of the certain document from the sending fax machine 10-1.

[0037] In some instances, the receiving fax machine 10-2 may transmit, to the user via the user’s email address, response information 107 on the reception state for the fax transmission operation. The user may confirm the reception state for the fax transmission operation of the certain document by checking an email on a device capable of reading emails.

[0038] FIG. 2 is a flowchart of an operation method of a fax machine that transmits fax data and receives response information on a reception state for a fax transmission operation, based on setting information in which a method of confirming the reception state for the fax transmission operation can be set, according to an example.

[0039] Referring to FIG. 2, the fax machine may receive first setting information to check a reception state of a recipient of a first document, in operation 210 of the fax machine.

[0040] For example, the first setting information may include information for requesting confirmation of the reception state of the recipient of the first document. In some examples, the information for requesting the confirmation of the reception state of the recipient of the first document may include information in which a method of confirming the reception state of the recipient of the first document can be set. For example, the first setting information may include information for setting a method of confirming a reception state for a first fax transmission operation of the first document.

[0041] In some examples, the first setting information may include at least one of information on a method of receiving response information on the reception state for the first fax transmission operation and information on a type of the response information. For example, the method of receiving the response information on the reception state for the first fax transmission operation may include a method of receiving the response information by email, a method of receiving the response information by fax machine, and the like. In some examples, the type information on the response information may include first type information for giving a confirmation of the reception state for the first fax transmission operation, and second type information for giving, after signing, a confirmation of the reception state for the first fax transmission operation.

[0042] In some examples, the first type information for giving a confirmation of the reception state for the first fax transmission operation may include a response type in which a receiving fax machine displays a preview image corresponding to first fax data and gives a confirmation of the preview image. For example, in an example where information included within the first fax data may be allowed to be disclosed to a plurality of users, a response of the first fax transmission operation may be set as the first type information.

[0043] In some instances, the second type information for giving, after signing, a confirmation of the reception state for the first fax transmission operation may include a response type in which a receiving fax machine displays a preview image corresponding to the first fax data and gives a confirmation of the preview image with a signature. For example, the receiving fax machine may display an input field for receiving a signature of the recipient. In some examples, if a recipient of the information included within the first fax data is a specific person, the response of the first fax transmission operation may be set as the second type information. If the information included in the first fax data requests the signature of the recipient, response of a second fax transmission operation may be set as the second type information, in some instances.

[0044] In some examples, the first setting information may be recorded in a first field within a pre-designated protocol. For example, the protocol may refer to a protocol for a communication method when transmitting or receiving data or information between fax machines. The protocol for a communication method may refer to an agreement on at least one of connection between fax machines, a transmission method, a communication method, data to be transmitted and received, information format, an error detection method, a code conversion method, and a transmission speed. In some examples, the protocol may include protocol T.30. For example, the first setting information may be stored in an optional message field within a predesignated protocol. Descriptions of fields of the protocol are given with reference to FIG. 5.

For example, the response information on the reception state for the first fax transmission operation may include at least one of information on whether or not reception of the first fax data is completed, information on a time at which the reception of the first fax data is completed, information on whether or not the first fax transmission operation is successful, and information on verification of the recipient of the first fax data. In some examples, the signature of the recipient of the first fax data may be included in verifying the recipient of the first fax data.

[0045] In some examples, if security is requested for the first document, the fax machine may receive second setting information for setting at least one of security level information for the first document, and authentication information according to the security level. For example, if the recipient of the first document is an unspecific person, the security level may be set as a low level, if the recipient of the first document is an unspecific person of a certain group, the security level may be set as a middle level, and if the recipient of the first document is a specific person, the security level may be set as a high level. For instance, if the security level is the middle or high level, the receiving fax machine may be set to perform authentication when receiving the first fax data of the first document. In some examples, an authentication method may include a method of entering an authentication number, a method of entering a password, and the like.

[0046] The fax machine, in some examples, may obtain first image data corresponding to the first document, in response to a request of the first fax transmission operation, in operation 220 of the fax machine.

[0047] For example, the fax machine may obtain the first image data corresponding to the fist document, based on a scan operation of the first document For instance, the first image data may include digital codes. The first image data may include a machine language readable by a processor within the fax machine.

[0048] In some examples, information that the first fax transmission operation requests may include at least one of the first fax data to be sent to the first fax transmission operation, information on the recipient to receive the first fax data, and information on the sender to send the first fax data. In some instances, information on the recipient may include email address information or fax number information of the recipient to receive the first fax data.

[0049] The fax machine, in some examples, may obtain the email address information or the fax number information to receive the response information on the reception state for the first fax transmission operation, based on a result of reading the first image data. For example, the fax machine may extract email address information or fax number information to receive the response information from the first image data, based on an optical character recognizer (OCR).

[0050] The fax machine, in some examples, may send the first fax data including first setting data corresponding to the first setting information, and the first image data to the receiving fax machine, in operation 230 of the fax machine.

[0051] In some examples, the fax machine may receive, from the receiving fax machine, the response information on the reception state for the first fax transmission operation, based on the first setting information, in operation 240 of the fax machine.

[0052] For example, if the method information included within the first setting information can be set as a method of transmitting the response information to the sending fax machine, the fax machine may receive, from the receiving fax machine, the response information on the first fax transmission operation.

[0053] In some examples, the response information on the reception state for the first fax transmission operation may include at least one of information on whether or not reception of the first fax data is completed on the receiving fax machine, information on a time at which the reception of the first fax data is completed, information on whether or not the first fax transmission operation is successful, and information on the signature of the recipient of the first fax data. For example, success or failure of the first fax transmission operation may have to do with whether or not the first document is properly received.

[0054] In some examples, the fax machine may display the response information on the reception state for the first fax transmission operation through a user interface unit of the fax machine. In addition, the fax machine may output a document in which the response information on the reception state for the first fax transmission operation is recorded.

[0061] Referring to FIG. 4B, the fax machine may display items for types that respond that the receiving fax machine has received the fax. For example, the types for responding that the receiving fax machine has received the fax may include a first type for confirming a reception state and simply giving a confirmation of a result of the reception state and a second type for confirming the reception state and giving, after signing, a confirmation of the result of the reception state. In some examples, the first type may be displayed as an item for a "request for a reply with respect to the reception result ", and the second type may be displayed as an item for a "request for a reply after signing" 421. In some examples, the types that respond that the receiving fax machine has received the fax may include a third type that does not give any response with regard to the reception state. For example, the third type may be displayed as an item "disabled".

[0062] In some instances, if an input for selecting an item for a certain type from among items for types that respond that the receiving fax machine has received the fax, the fax machine may display items for methods of receiving the response information. For example, the methods of receiving the response information may include a method of receiving the response information by email and a method of receiving the response information by fax. In some examples, if an input for selecting the item for a "request for a reply after signing" 421 is received, the fax machine may display an item for a "reply by email", and an item for a "replay by fax". If an input for selecting the item for a "reply by fax" is received, the fax machine may display an input field 422 for receive a fax number.

[0063] Referring to FIG. 4C, the fax machine, in some examples, may display a user interface 431 for setting information on a method of receiving response information on a reception state for a fax transmission operation, and information on types of the response information on the reception state for the fax transmission operation.

[0064] For example, in terms of the information on the method of receiving the response information on the reception state for the fax transmission operation, the fax machine may display items for "email", "fax", and "disabled".
