Abstract

If a fax machine cannot receive self-recovery while receiving fax data from any destination, check whether the modem function is normal. If the modem function is normal, dial any destination phone number entered by the user. After the call path is connected, the fax data is resent to any destination.

Therefore, when a malfunction occurs in other components except the modem and the fax cannot print the received fax data normally, the fax data can be retransmitted to an arbitrary destination, thereby preventing the loss of the fax data.

Description

How to Resend Fax Received Data

The present invention relates to a method for retransmitting a fax data of a fax, and more particularly, in a fax of a destination that has received fax data from a transmission destination, when a failure that cannot be self-recovered occurs in a component other than a modem, The present invention relates to a fax data retransmission method of a facsimile so that the fax data can be output by retransmission to an arbitrary destination.

In general, the fax outputs fax data received from any destination via a telephone line (PSTN) or allows the user to send fax data to any destination via the same phone line. One device. Such a facsimile typically includes functions of a scanner, a printer, and a telephone, and is widely used in homes and offices as the most popular office automation equipment in recent years.

In recent years, as fax communication becomes general, much information is exchanged through facsimile. Especially for documents that need to be processed quickly, the exchange of information through facsimile is very effective, thereby greatly improving work efficiency.

As information exchange through facsimile is frequently performed, memory is installed in the facsimile to improve the reception rate of the information or to receive a large amount of information. This enables memory transmission / reception of specific documents.

A conventional facsimile receives fax data transmitted from a transmission destination and prints it in page units. In this case, when a failure occurs in the printer of the facsimile, the received fax data cannot be printed, and thus the received fax data is sequentially stored in the memory.

In general, in case of a failure that occurs in the facsimile, which is easily recoverable by the user (jam, out of paper, out of toner, etc.), the fax data received in the memory is sequentially stored as the user recovers it. Since it is printed, the receiving operation of the fax data can be normally performed.

By the way, according to such a conventional facsimile, the following problem arises.

In other words, if a fax error occurs that cannot be easily repaired by the user, that is, a malfunction that needs to be repaired while the power is turned off (fuse error, printer error, etc.), the fax data stored in the memory is turned off and lost. do.

Accordingly, the present invention is to solve such a problem, the object of the present invention is that if the facsimile fails to print the received fax data normally due to a failure in other components except the modem, the fax data is random The present invention provides a method of retransmitting a fax data of a fax so as to prevent loss of the fax data by retransmitting to a destination.

A feature of the present invention for achieving the above object is a facsimile fax data retransmission method comprising a modem for receiving fax data from a transmission destination and transmitting the fax data to an arbitrary destination, and a printer for printing the received fax data. A first checking step of, when the fax data retransmission mode is selected, checks whether the received fax data is normally output by communicating with the printer; A second checking step of checking whether the modem is normally operated if the fax data is not normally output; A connection step of accessing a telephone line by dialing by receiving a telephone number of an arbitrary destination when the modem is normally operated; And a transmission step of retransmitting the received fax data to the arbitrary destination when the call path is connected.

Preferably, the second checking step further includes a storing step of storing the fax data if the fax data is not normally output.

Hereinafter, a preferred embodiment of the fax data retransmission method of the fax according to the present invention will be described in detail with reference to the accompanying drawings.

1 shows a schematic block diagram of a facsimile applied to the present invention.

The facsimile as shown in FIG. 1 includes a central processing unit 1 which generally controls the facsimile according to a set program, program data, protocol data, text data, and work related to transmission and reception. A memory 2 for accessing or storing data under the control of the central processing unit 1, and a plurality of keys for generating the key data of the facsimile, and when the key data is generated, the central processing unit 1 An OPEN (Operational Panel) 3 including a display device for inputting the data into the central processing unit 1 and displaying the display data of the central processing unit 1, and converting the original data into digital image data. Under the control of the scanner 4 and the central processing unit 1 provided to the central processing unit 1, the output data of the central processing unit 1 is modulated and output in analog form, and Modem (5) demodulating and outputting the input signal of the state, and is operated under the control of the central processing unit (1) to form a call loop (composed of Ring and Tip) of the general telephone network (modem 5 and general) A network control unit (NCU) 6 for interfacing the signals of the telephone network, a printer 7 for printing fax data received by a control signal from the central processing unit 1, and a remaining amount of recording paper is sensed. Or a sensor unit 8 for detecting a document and providing it to the central processing unit 1.

Each of these components is the same as the configuration of a general facsimile, so a detailed description thereof will be omitted, and will be described in detail the essential components applied to the present invention.

Referring to Figure 2 with respect to the operation of the present invention having such a configuration as follows.

When the user selects the fax data retransmission mode using any of the function keys of the operation panel 3 (S1), the central processing unit 1 communicates with the printer 7 to output the received fax data. It is determined whether the state is normal (S2). Here, if it is determined that the received fax data is normally output, this means that the user can confirm the received fax data, thus ending all the processes.

If it is determined that the received fax data is not normally output in step 2 (S2) above, it means that a failure has occurred in the printer 7 and related parts, so it is checked whether the fax data is stored in the memory 2. (S3). Here, if it is determined that the fax data is not stored in the memory 2, this means that the fax data is not normally received or the fax data to be received no longer exists, thus terminating all the processes.

If it is determined in step 3 (S3) that the fax data is stored, the central processing unit 1 checks whether the modem (5) is operating normally (S4). Here, if it is determined that the modem 5 does not operate normally, it indicates that the user cannot perform the fax data retransmission mode selected by the user, and therefore the central processing unit 1 outputs an error message on the display window of the operation panel 3. After (S5), all processes are finished.

On the other hand, if it is determined in step 4 (S4) that the modem 5 operates normally, it receives an arbitrary destination phone number from the user (S6), and controls the modem 5 to dial the corresponding phone number (S7). ). Thereafter, it is determined whether the call path is connected (S8), and when the call path is connected, the central processing unit 1 retransmits the fax data stored in the memory 2 to any set destination (S9).

Then, when the transmission operation of the fax data is completed (S10), the central processing unit 1 controls the modem 5 to cut off the communication path (S11), and ends all processes.

Therefore, when a failure that cannot be self-recovered occurs in other components except the modem 5, it is possible to prevent the loss of the received fax data by retransmitting the received fax data to an arbitrary destination.

As a result, according to the fax data retransmission method of the present invention, there are advantages as follows.

That is, when a malfunction occurs in other components except the modem and the facsimile cannot print the received fax data normally, loss of the fax data can be prevented by retransmitting the fax data to an arbitrary destination.
