Abstract

[Technical field to which the claimed invention belongs]

It is a technology that stops printing when black data of a line or more that is set while receiving image data in a fax is continuously received.

[Technical Problem to Solve]

Receiving black image data continuously over the line set in the fax The receiving document is printed in black. Due to excessive printing, the toner hopper needs to be replaced before the set number of sheets, so the lifespan of the consumable parts is shortened and maintenance costs are increased. Solve the problem.

[Summary of the solution of the invention]

If the fax is ring-received and black image data of more than the line continuously set when receiving image data, image data printing is stopped and an error is generated.

[Important Uses of the Invention]

It is used to stop printing on continuous reception of black data due to user error or error in the fax.

The present invention relates to a method of stopping printing upon receiving abnormal data from a facsimile, and more particularly, to a method of stopping printing when black data of a line or more set during image data reception is continuously received.

In general, a facsimile detects a ring signal at the time of ring arrival and then receives and prints image data through a protocol. Thus, in the case of the plain paper fax machine among the faxes for printing the image data, the developer including the OPC drum as a consumable and the toner hopper for supplying the toner are used for a predetermined number of times of use. However, if the sender accidentally transmits the document upside down, when the back side of the document is colored, only the black image data is continuously printed from the receiving fax machine, so the entire receiving document is printed in black. As a result, excessive toner is used during printing, and the toner hopper needs to be replaced before the set number of sheets is used. Therefore, the lifespan of consumable parts is shortened and maintenance costs are increased. In the case of the facsimile using the thermal print head (TPH), there is a problem that the thermal print head is overheated and the product may be damaged.

Accordingly, an object of the present invention is to provide a method of stopping printing when black data of a line or more set in receiving image data is continuously received in order to solve the above problems.

In order to achieve the above object, the present invention provides a method for receiving image data by performing a ring-to-ring protocol, and stopping printing of image data when the received image data is continuously black over the set line and error message. Characterized in that the process of displaying.

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

1 is a block diagram of a facsimile system according to an embodiment of the present invention. The central processing unit controls the system according to a predetermined program and controls printing to be stopped when there is continuous black data or more in a line set when receiving image data. 10,

A memory unit 20 storing a program for intermediate printing when printed with protocol data and black data over a set line, and accessing data under the control of the CPU 10;

An OPE (OPERRATION PANNAL) 30 having a plurality of keys capable of generating various key data such as a dial key and a function setting key of the system, and including a display device for displaying data;

A scanner 40 which scans an image of an original and converts it into digital image data and provides the same to the central processing unit 10;

A modem 50 which is controlled by the central processing unit 10 and modulates the output data of the central processing unit 10 into analog data, and demodulates and outputs the analog receiving data into digital data;

Operated by the control of the central processing unit 10 to form a telephone line (Tel-Line) call loop, the NCU (NETWORK) for interfacing the signal of the modem 50 and the signal of the telephone line (Tel-Line) CONTROL UNIT) (60),

The printer 70 is configured to print received data in response to a control signal of the central processing unit 10.

2 is a control flowchart for stopping printing upon continuous black data reception according to an embodiment of the present invention.

Receiving image data by performing a protocol when receiving a ring;

When the received image data is black data more than a setting line continuously, the printing of the image data is stopped and an error message is displayed.

One preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 2.

First, in step 101, the central processing unit 10 detects whether there is a ring arrival from the ring detection unit of the NCU 60, and proceeds to step 102 if there is a ring arrival. In step 102, the central processing unit 10 proceeds to the protocol and proceeds to step 103. In step 103, the central processing unit 10 checks whether image data is received, and proceeds to step 104 when image data is received. In step 104, the CPU 10 clears the black line counting value and proceeds to step 105. In step 105, the central processing unit 10 checks whether the printing data exists and proceeds to step 106 if the printing data exists. In step 106, the CPU 10 calculates a black data ratio of the printing data of one line. The black data ratio is calculated by the following equation.

As such, the central processing unit 10 checks whether the calculated black data ratio is 90% or more in step 107 by calculating the black data ratio among the printing data of one line. If it is abnormal, the process proceeds to step 108. In step 108, the central processing unit 10 regards the entire line as black data, increases the number of black lines by 1, and proceeds to step 109. In step 109, the central processing unit 10 checks whether the total number of black lines is 50 mm or more. That is, if the black line is continuously 50 mm or more, and if it is not 50 mm or more, the process proceeds to step 110, and the normal line and image data are printed, and the process returns to step 105. However, if it becomes 50 mm or more in step 109, it is regarded as abnormal image data, and the flow proceeds to step 111 to stop the printing operation and generate an error message.

As described above, if the image is received by the facsimile ring and the black image data is longer than the line set continuously when the image data is received, the image data printing is terminated and an error message is generated. There is an advantage of preventing waste of paper or toner.
