Description

Method for printing of scanning data in the MFP}

The present invention relates to a method of printing scanning data in a multifunction device, and more particularly, when a scanning data of an original is stored in a memory to copy an original in the multifunction device, a memory full in which there is no memory capacity occurs. The present invention relates to a method of printing scanning data in a multifunction printer that directly prints the data to a printer without storing the scanning data in a memory.

In general, a multifunction device refers to a device that performs not only a function of a printer for printing data or an original input from a computer, but also a function of a facsimile for transmitting an image document to another place through a communication line. That is, such a multifunction device is a multi-function terminal made by weaving existing terminal devices such as a facsimile or a printer into a single unit, and has a function of interworking with a PC, that is, a device having a PC-interface function.

In the method of copying an original using a function of a printer provided in such a multifunction device, as shown in FIG. 1, after setting an original to be copied on the document feeder, a copy key is input (S10). The fed document is fed one by one, and the fed document is scanned (S11). The scanned data is stored in the memory (S12), and it is checked whether a recordable area of the memory exists (S13).

If the recordable area of the memory does not exist while storing the scanning data of the original in the memory as a result of the check, after displaying the message "memory full" to the user (S16), the memory copy is terminated, and the check result is recorded. If the available area exists, it is checked whether all scanning data of the original is stored in the memory (S14).

If all of the scanning data of the original has been stored in the memory, the data stored in the memory is printed (S15) and then ends.

In this way, when the multifunction device uses the printer function to store the scanning data of an original in the memory and performs a memory copy for printing the data stored in the memory, a large amount of data cannot be stored in a system having a small memory. .

Therefore, when memory copying is performed in a system having a small memory size, the recordable area of the memory is exhausted before the scanning data of the original is stored, and a memory pool is generated, thereby terminating the memory copy operation.

In such a case, the user may inconvenient to print the data stored in the memory to secure the recordable area of the memory and then perform the above memory copying operation.

Accordingly, an object of the present invention is to solve such a problem, and an object of the present invention is to perform a direct copy to print scanned data while scanning an original when the recordable area of the memory is exhausted during the memory copy. The present invention provides a method of printing scanning data in a multifunction apparatus capable of printing more original data in a system having a smaller size.

FIG. 2 is a schematic block diagram of a general MFP applied to the present invention, FIG. 3 is a flowchart illustrating the printing of scanning data in the MFP according to the present invention, and FIG. 4 is a memory showing the configuration of a memory. The map is shown.

Referring to FIG. 2, the controller 100 generally controls the system according to a set program. In particular, the controller 100 controls each unit to perform a direct copy when the recordable area of the memory unit 110 is exhausted during the memory copy.

The memory unit 110 stores an operation program, a general control program, and data according to program execution of the controller 100, and accesses or stores data under the control of the controller 100.

Here, referring to FIG. 4, the configuration of the memory unit 110 includes a user memory 111 that stores coded data scanned by the scanning unit 130 and passed through an encoder (not shown). A print memory 112 for storing data to be printed by the print unit 160, a scan memory 113 for storing raw data scanned by the scanning unit 130, and And a system data area 114 that stores the variables needed to run the system.

The operation panel 120 includes a plurality of keys to generate key data of the multifunction device, and inputs them to the control unit 100 when key data is generated and to display the display data of the control unit 100. The display device 125 is included.

The scanning unit 130 scans the data of the document in a flat-bed manner, converts the data into digital image data, and provides the data to the control unit 100.

The modem 140 modulates and outputs the output data of the controller 100 in an analog form under the control of the controller 100, demodulates and outputs an analog input signal, and the NCU 150 controls the controller ( It is operated under the control of 100) to form a call loop of the Public Switching Telephone Network (PSTN) consisting of Ring and Tip, and interfacing the signal between the modem 140 and the general telephone network.

The interface unit 180 is a medium connecting the computer and the multifunction device to receive data to be printed from the computer.

An operation of the present invention having such a configuration will be described in detail with reference to FIG. 3.

After setting the original to be copied by the user, if a key for performing memory copying is selected (S301), the controller 100 controls the scanning unit 130 to scan the set original (S302).

The scanning data of the original is stored in the user memory 111 of the memory unit 110 (S303), and it is checked whether a recordable area of the user memory 111 exists (S304).

If there is a recordable area of the user memory 111 as a result of the check, the controller 100 checks whether scanning of all originals is completed (S305).

If the scanning operation of all the originals is not completed as a result of the check, the process returns to step 302 (S302) of scanning the set originals. If the scanning operation of all the originals is completed, the control unit 100 controls the printing unit 160. After the data stored in the user memory 111 is printed (S306), the process ends.

On the other hand, as a result of checking in step 304 (S304) of confirming whether a recordable area of the user memory 111 exists, the user memory 111 is stored while the data scanned by the scanning unit 130 is stored in the user memory 111. If the writable area of the user memory 111 does not exist, the controller 100 displays a message (eg, “memory full”) indicating that the writable area of the user memory 111 is exhausted on the display device 125 of the operation panel 120. The user is notified (S307) and the scan operation for performing the memory copy is stopped (S308).

The control unit 100 stops the scan job for memory copying, and then directly prints the data scanned by the scanning unit 130 in the memory copy in the user memory 111 without printing the data in the user memory 111. The setting state of the recopy flag for switching to copying is checked (S309).

As a result of the check, if the recopy flag is set to '0', the process is terminated. If the recopy flag is set to '1', the data on the page in which the memory pool is generated during the memory copy is deleted from the user memory 111 ( S310). Here, the re-copy flag is set by the user, and the user may set the re-copy flag to '1' by using a preset key provided in the operation panel 120 before the print job.

Subsequently, the controller 100 controls the scanning unit 130 to scan from the page where the memory pool is generated (S311), and print memory for storing the data for printing the scanned data without being stored in the user memory 111 ( 112, and the print unit 160 prints data stored in the print memory 112 under the control of the controller 100 (S312).

The control unit 100 checks whether the scanning operation of all originals is completed (S313), terminates when scanning of all originals is completed, and scans the set originals if scanning of all originals is not completed (S311). Return to).

Here, when the direct copy is completed, the data stored in the user memory 111 may be printed through the print unit 160 while the memory copy is performed.

Therefore, the copy function can be used regardless of the data amount of the original, thereby providing convenience in use.
