Abstract

Disclosed is a method to supply paper manually within a printer. The method comprises 3 steps. In the first step, a tray sensor senses whether the paper is supplied. In the second step, the paper is fed until the register roller and the fit roller hold tightly the paper. In the third step, the printing is performed when the paper is sensed in the first step, or the feeding is completed in the second step. Thereby, the printing can be smoothly performed.

프린터에 있어서 수동 급지 방법Manual Feeding Method in the Printer

제1도는 레이저 프린터 구동 시스템도.1 is a laser printer driving system diagram.

제2도는 종래의 흐름도.2 is a conventional flow chart.

제3도는 본 발명에 따른 흐름도.3 is a flow chart according to the present invention.

제4도는 레이저 프린터의 개략도.4 is a schematic view of a laser printer.

본 발명은 레이저 프린터에 있어서 수동 급지 방법에 관한 것으로, 특히 기존의 수동 트레이를 없애고 수동 급지 센서에 의해 종이 감지시 레지롤러 또는 종이를 홀딩할 수 있을때까지 종이를 피이딩시켜 프린팅하는 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual feeding method in a laser printer, and more particularly, to a method of feeding and printing a paper until the existing manual tray can be removed and the regenerative roller or paper can be held when the paper is detected by the manual feed sensor. .

일반적으로 제4도와 같이 수동 급지 트레이(408)를 사용하는 레이저 프린터, LED 프린터, 버블제트 프린터에서 프린팅일시 수동 트레이(408)를 세팅시켜서 그 위에 종이를 올려 놓아 프린팅 명령을 받게 되면 프린팅된다. 즉, 제1도와 같이 프린터 시스템의 각 부를 제어하는 CPU(102)에서 센서부(103)의 트레이 장착여부를 감지하는 센서로부터 감지하여 (2a)과정에서 수동 트레이(408)가 세팅되어 있는가를 체킹한다.In general, in the laser printer, the LED printer, and the bubble jet printer using the manual paper feed tray 408 as shown in FIG. 4, the manual tray 408 is set and printed on the paper. That is, as shown in FIG. 1, the CPU 102 controlling each unit of the printer system detects whether the sensor unit 103 is mounted in the tray, and checks whether the manual tray 408 is set in step 2a. .

상기 (2a)과정에서 CPU(102)가 센서부(103)로부터 종이가 있는지의 유무를 감지하여 수동 트레이(408)에 종이가 없을때 (2c)과정에서 종이가 없음을 경보 및 표시부(107)를 통해 에러 메세징한다.In the process (2a), the CPU 102 detects the presence or absence of paper from the sensor unit 103, and when there is no paper in the manual tray 408, the alarm and display unit 107 indicates that there is no paper in the process (2c). Error messages via

그러나 상기 (2a, 2b)과정에서 수동 트레이(408)가 세팅되어 있지 않거나 수동 트레이(408)에 종이가 있을시 (2d, 2e)과정에서 CPU(102)는 인터페이스회로(105)를 통해 퍼스널 컴퓨터(106)로부터 프린팅 명령이 있는가를 체킹한다.However, when the bypass tray 408 is not set in step (2a, 2b) or when there is paper in the bypass tray 408, in step (2d, 2e), the CPU 102 uses the personal computer through the interface circuit 105. Check from 106 to see if there is a printing command.

상기 (2d, 2e)과정에서 프린팅 명령어 입력이 있을때 (2f)과정에서 카세트(409)로부터 용지를 피이딩하여 프린팅하고, (2g)과정에서 수동 트레이(408)상의 종이를 피이딩하여 프린팅하도록 되어 있다. 그러므로 수동으로 급지하는 용지에 프린팅하기 위해서는 수동 트레이가 필요하게 되며, 수동 트레이 용지가 세팅되어 있는 경우 카세트에서 급지하지 못하도록 하는 기구적인 설계가 필요로 하거나 복잡한 것이 필요한 경우 설정해야 하는 문제점이 있었다.When the printing command is input in the process (2d, 2e), the paper is fed from the cassette 409 and printed in the process (2f), and the paper is fed by the paper on the bypass tray 408 in the process (2g). have. Therefore, in order to print on the paper to be fed manually, the manual tray is required, and when the manual tray paper is set, there is a problem that a mechanical design that does not allow feeding from a cassette or a complicated one is required to be set.

따라서 본 발명의 목적은 수동 트레이 없이 수동 피이딩 프린팅이 가능한 방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a method capable of manual feeding printing without a manual tray.

이하 본 발명을 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 발명에 따른 흐름도로서, 프린터에 전원이 인가되면 각부 전원이 공급되어 초기화 상태로 된다. 이때 또한 CPU(102)도 각 포트를 초기화하고 ROM(101)의 제어 프로그램 데이타를 CPU(102)의 처리 영역으로 옮겨 명령이 입력에 따른 동작을 수행하도록 한다. 센서부(103)에서 수동 급지 트레이 센서의 종이 감지유무를 CPU(102)에서 (3b)과정에서 체킹한다.3 is a flowchart according to the present invention. When power is applied to the printer, power is supplied to each unit to be in an initialization state. At this time, the CPU 102 also initializes each port and moves the control program data of the ROM 101 to the processing area of the CPU 102 so that the command performs an operation according to the input. The sensor unit 103 checks whether paper is detected by the manual feed tray sensor in the CPU 102 in the process (3b).

상기 (3b)과정에서 종이감지가 센싱될 때 (3d)과정에서 급지 모터구동부(104)를 제어하여 종이를 레지롤러 또는 피트롤러가 종이를 잡고 있기 충분한 정도까지 피이딩한다. 상기 (3b)과정에서 종이가 감지되지 않을때나 (3d)과정에서 종이 피이딩이 완료되었을 때 (3c)(3e)과정에서 인터페이스회로(105)를 통해 퍼스널 컴퓨터(106)로부터 프린팅 코멘드 입력여부를 체킹한다. 상기 프린팅 명령어의 입력이 있을시 (3f)과정에서 프린팅이 진행된다.When the paper sensing is sensed in step (3b), the paper feed motor driver 104 is controlled in step (3d) to feed the paper to a degree sufficient to hold the paper. When paper is not detected in step (3b) or when paper feeding is completed in step (3d), whether a printing command is input from the personal computer 106 through the interface circuit 105 in step (3c) or (3e). Check. When there is an input of the printing command, printing is performed in step 3f.

상술한 바와 같이 종래의 수동 트레이를 없애고 수동 급지센서에서 종이가 감지되면 레지롤러 또는 피트롤러가 종이를 잡고 있기 충분한 정도까지 용지를 피이딩하여 프린팅을 원활히 할 수 있는 이점이 있다.As described above, when the paper is detected by the manual feed sensor by removing the conventional manual tray, there is an advantage that the printing may be smoothed by feeding the paper to a degree sufficient to hold the paper.
