Abstract

The present invention receives print data from the outside through a communication network, restores the received data to bitmap data, which is an image to be printed, and stores the restored bitmap data in a memory and prints the same to a printer. When a paper jam occurs during the storage / printing of the received data, the operation of transmitting the data to the printer is stopped and memory reception to be stored in the memory is continued. When the paper jam is removed, the data stored in the memory is printed.

Accordingly, according to the data receiving method of the multifunction device, since the received data is stored in the memory and printed by the printer, even if a paper jam occurs during printing with the printer, it can be continuously received into the memory. Since the data received by the printer can be printed by the printer, there is an advantage of not having to re-receive a document having a paper jam.

Description

Method and device for receiving data of multifunction device

The present invention relates to a method and apparatus for receiving a data of a multifunction device, and more particularly, by storing data received from the outside through a communication network in a memory and simultaneously printing the data to a printer, thereby continuing to receive the memory even if a paper jam occurs during printing. The present invention relates to a data receiving method and apparatus of a multifunction apparatus for printing data stored in a memory when a jam is cleared.

In general, the multifunction device is a multifunctional terminal that is implemented by integrating the existing office equipment, namely, terminals existing in each unit such as a facsimile machine, a scanner, a printer, and a copier into a single device. Used in conjunction with a computer.

The facsimile embedded in the multifunction device transmits and receives data through the communication network. When data is received from the transmitter, the modem restores the compressed data into bitmap data and stores it in a buffer in the modem. The data stored in the buffer is sent to the printer line by line. The transmitted data is deleted from the buffer and the next data is shifted.

If a paper jam occurs while printing the data received through the above process, the next data cannot be printed, so that the sender is notified of the occurrence of an error, and the reception is stopped.

In addition, a multifunction printer with a built-in memory stores the received data in the memory only when there is no paper to record the data while the received data is restored by the modem and printed by the printer.

However, according to the data receiving method of the all-in-one, the received data is restored by the modem and sent directly to the printer for printing. If a paper jam occurs during printing, the next data cannot be printed. After the jam is cleared, the sender needs to resend the document to receive the document again. In this case, the reception of the document is delayed.

Accordingly, an object of the present invention is to solve the above problems, and an object of the present invention is to store received data in a memory and print the data to a printer at the same time so that the data is continuously received and stored in the memory even if a paper jam occurs during printing. When the paper jam is cleared, the data stored in the memory is printed to prevent the loss of data.

And continue to receive the memory, and transmit the data stored in the memory to the printer to print when the paper jam is cleared.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically showing a multifunction apparatus applied to the present invention.

The central processing unit 1 controls the system as a whole and, in particular, stores the received data and simultaneously stops the printing operation when a paper jam is detected during printing, and prints the data stored in the memory when the paper jam is removed. .

The memory 2 is composed of an EPROM in which the entire system program is embedded, an SRAM for processing system data, a DRAM for receiving print data and a memory, and detected by the program data, protocol data, character data, and sensor unit 3. The page in which the jammed paper is generated is stored and the data is accessed or stored under the control of the central processing unit 1.

The sensor unit 3 detects the remaining amount of recording paper, the document to be transmitted, and the presence of a paper jam, and provides the same to the central processing unit 1.

The operation panel (OPE) 4 includes a plurality of keys capable of generating key data of the system, inputs them to the central processing unit 1 when key data is generated, and displays the display data of the central processing unit 1. And a display device capable of doing so.

Under the control of the central processing unit 1, the modem 5 modulates and outputs the output data of the central processing unit 1 in analog form, and demodulates and outputs the analog input signal. In particular, the modem 5 has a built-in line buffer. The compressed data received from the outside through the NUC 6 is restored to bitmap data and temporarily stored in the line buffer. The temporarily stored bitmap data is stored in the memory 2 at the same time by the control of the central processing unit 1 and transmitted to the printer 7 at the same time. The data stored / transmitted is deleted and then The data is shifted sequentially.

The network control unit (NCU) 6 is operated under the control of the central processing unit 1 to form a call loop of a public switching telephone network (PSTN) (consisting of rings and tips) and a modem ( 5) and the signal of the general telephone network.

The printer 7 prints the data transmitted from the modem 5 under the control of the central processing unit 1, the scanner 8 scans the image of the original, converts it into digital image data, and then the central processing unit 1 ), The speaker 9 generates an alarm by the control signal output from the central processing unit (1).

The operation of the present invention having such a configuration will be described in detail with reference to FIG.

2 is a flowchart illustrating a data receiving method of a multifunction apparatus according to the present invention.

It is determined whether a ring signal is received from the transmitter through the NUC 6 (S110), and if the ring signal is not received, the standby state is maintained (S120). When the ring signal is received in step S110, after exchanging protocols (S130), data is received (S140). The received data is demodulated by the modem 5 and restored to bitmap data which is an image to be printed (S150), and the restored bitmap data is stored in the memory 2 and printed by the printer 7 (S160).

Check whether the printing operation of the restored bitmap data is completed (S170), and if printing is not completed, search whether a paper jam has occurred through the sensor unit 3 (S200).

As a result of the search, if a paper jam occurs while printing the restored bitmap data, the operation of transferring the converted bitmap data to the printer 7 from the modem 5 is stopped and stored only in the memory 2 (S310). .

It is determined whether the storage of the converted bitmap data is completed (S320). When the storing of the verification result data is completed, it is determined whether the paper jam is removed through the sensor unit 3 (S330).

As a result of the determination, when the paper jam is removed through the sensor unit 3, the bitmap data stored in the memory 2 is transmitted to the printer 7 for printing (S340), and then ends.

On the other hand, if the storage of the bitmap data is not completed in the memory 2 as a result of the check in step S320, it is searched whether a recordable area of the memory 2 in which the bitmap data is stored exists (S350).

As a result of the search, when the recordable area of the memory 2 is exhausted, the corresponding page in which the paper jam detected by the sensor unit 3 is detected is detected (S360), and whether the data of the previous page is present than the detected page is compared ( S370).

As a result of the comparison, if the data of the previous page exists, since the data of the previous page is already printed by the printer 7, it is deleted from the memory 2 (S380), and when the deletion of the previous data is completed (S390), step S310 Repeat from now on.

As a result of the comparison, if the data of the previous page does not exist, there is no data printed by the printer 7, and there is no data to delete, and since the recordable area of the memory 2 is exhausted, it can be stored in the memory 2. Therefore, after displaying an error message on the display device of the operation panel 4 (S400), reception is terminated.

Thus, according to the data receiving method of the multifunction apparatus according to the present invention has the following advantages.

First, since the received data is stored in the memory and simultaneously printed by the printer, even if a paper jam occurs during printing with the printer, it can be continuously received into the memory.

Secondly, if the paper jam occurred while printing to the printer, the data received in the memory can be printed to the printer, so that the paper jam does not need to be received again.
