Description

인쇄기{Printer}Printer {Printer}

본 발명은 인쇄기에 관한 것으로서, 상세하게는 인쇄지시명령을 접수하면 현재 남아 있는 잉크로부터 인쇄가능한 용지의 인쇄매수를 알려줄 수 있도록 된 인쇄기에 관한것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing press, and more particularly, to a printing press that is capable of informing the number of printable sheets of printable paper from the ink remaining upon receipt of a printing instruction.

일반적으로 레이저 프린터나 복사기와 같은 전자사진방식 인쇄기는 노광에 의해 정전 잠상이 형성되어 있는 감광매체에 고체상태의 현상물질인 토너 또는 액체상태의 잉크를 분사시켜 화상을 형성시킨 후, 그 감광 매체와 접촉되어 회전하는 롤러 사이로 용지 카세트에 적재된 용지를 급지하여 통과시킴으로써 원하는 화상을 인쇄할 수 있도록 되어있다. In general, an electrophotographic printing machine such as a laser printer or a copier forms an image by spraying a toner or a liquid ink in a solid developing material on a photosensitive medium on which an electrostatic latent image is formed by exposure, and then forming an image. A desired image can be printed by feeding and passing the paper loaded in the paper cassette between the rollers which come into contact and rotate.

한편, 이와 같은 인쇄기 예컨데 프린터는 케이블 또는 네트웍에 의해 접속된 사용자 컴퓨터에 인쇄작업이 가능한지와 관련된 상태정보를 제공하였다. 종래의 프린터에서 사용자 컴퓨터 등에 제공되던 상태정보의 예로서는 데이터 저장용 버퍼에 수신된 데이터가 가득 찼음을 알리는 비지(busy)신호, 용지가 없음을 알리는 엠프티(empty) 신호, 인쇄도중 종이가 걸려 있다거나, 그밖에 다른 중대한 문제가 생겨 더 이상 인쇄작업을 진행할 수 없다는 상태를 알려주는 고장신호 등이다. 따라서, 프린터로부터 제공되는 상기 상태정보를 판독한 컴퓨터는 이를 사용자에게 알려줌으로써 프린터의 인쇄작업이 가능하도록 하는 사용자의 적절한 조치가 취해질 수 있었다. On the other hand, such a printer, for example, a printer provided status information related to whether a print job is possible to a user computer connected by a cable or a network. Examples of status information provided to a user computer in a conventional printer include a busy signal indicating that the data received in the data storage buffer is full, an empty signal indicating that there is no paper, and a paper jammed during printing. Or a fault signal that tells you that there are other serious problems that you can't print anymore. Therefore, the user who reads the status information provided from the printer can inform the user of the user's actions to enable the printer to print.

상기 상태정보중 현상에 이용되는 잉크와 관련하여 종래에는 잉크 고갈, 또는 잔량확인용으로 제공하는 것으로서 정량적인 잉크잔량 표시가 아닌 설정된 한계량 이하에는 무조건 표시하도록 하는 잉크로우표시 등을 제공하였다. 그러나, 이러한 정보로는 실질적인 잉크잔량에 대한 인쇄가능매수를 사용자가 파악할 수 없어, 잉크로우표시를 확인하였다 하여도 현재 인쇄하고자 하는 인쇄분량에 대해 잔류 잉크만으로 인쇄를 마칠 수 있는지 아니면, 중간에 잉크를 보충해주어야 하는지를 알 수 없는 불편함이 있었다. Regarding the ink used for development in the state information, an ink low display is provided so as to display the ink unconditionally or below the set threshold amount, rather than quantitative ink remaining amount indication, which is provided for ink depletion or remaining amount confirmation. However, this information does not allow the user to determine the actual number of prints for the remaining ink level, and even if the ink low display is confirmed, it is possible to finish printing with only the remaining ink for the current printing quantity, or in the middle of the ink There was no inconvenience to know whether to supplement.

본 발명은 상기와 같은 문제점을 개선하기 위하여 창안된 것으로서, 잉크잔량에 대해 인쇄가능한 용지 매수를 산출하여 상태정보로서 제공할 수 있도록 된 인쇄기를 제공하는 데 그 목적이 있다. The present invention was devised to improve the above problems, and an object thereof is to provide a printing machine which can calculate the number of printable paper sheets with respect to the remaining ink level and provide them as status information.

The operation panel 15 is provided with function operation keys for various printing functions that can be set, and outputs an operation signal by the user's operation to the printer controller 11, and is usually installed outside the main body.

인쇄기 엔진(14)은 인쇄기 콘트롤러(11)에 의해 제어 및 구동되어 실질적인 인쇄를 담당하는 것으로서, 인쇄방식에 따라 그 구성요소에 차이가 있지만, 습식 레이저 컬러 프린터의 경우에는 롤러들에 의해 순환운동하도록 설치된 감광벨트에 광을 주사하여 정전잠상을 형성시키는 복수개의 광주사장치, 상기 정전잠상을 색상별로 현상하는 복수개의 현상기, 감광벨트상에 현상되어 있는 화상을 용지로 전사시키는 전사장치, 감광벨트상에 형성된 정전잠상을 지워 새로운 정전잠상을 기입할 수 있도록 초기화시키는 리셋장치가 구비된다.The printing press engine 14 is controlled and driven by the printing press controller 11 and is responsible for the actual printing. The printing engine 14 has a different component depending on the printing method, but in the case of a wet laser color printer, the rollers are circulated by the rollers. A plurality of optical scanning devices for scanning the light on the provided photosensitive belt to form an electrostatic latent image, a plurality of developing devices for developing the electrostatic latent image for each color, a transfer apparatus for transferring the image developed on the photosensitive belt to paper, and a photosensitive belt image There is provided a reset device for initializing the new electrostatic latent image to be erased by erasing the electrostatic latent image formed therein.

표시장치(13)는 인쇄기 콘트롤러(11)에 제어되어 지시된 정보를 표시한다.The display device 13 is controlled by the printer controller 11 to display the indicated information.

레벨검출부(20)는 인쇄기 엔진(14)의 현상기에 제공되는 현상용 잉크의 잔량정보를 제공할 수 있도록 된 것으로서, 다양한 방법에 의해 가능하고, 도시된 예에서는 잉크 보다 비중이 낮은 물질로 된 부유체(21)를 이용하여 저수된 잉크의 저수 레벨정보를 제공할 수 있도록 되어 있다. 힌지축(22)이 설치된 영역에서 상호 한몸체로 연결된 두 개의 아암(23)(24)중 하나의 아암(23)은 부유체(21)와 연결되어 있고, 다른 아암(24)의 이동 경로상에 포토인터럽터(26)가 설치되어 있다. 상기 포토인터럽터(26)는 검출하고자하는 저수레벨단위로 상기 아암(24)의 이동경로를 따라 라인상으로 다수 구획된 영역을 갖는 광검출기(27)와 상기 아암(24)의 일측에 설치되어 상기 광검출기의 구획된 단위 영역내로 광빔 스폿이 맺힐수 있도록 된 광원(28)을 갖는다. 따라서 용기(25)내 잉크의 저수레벨 변동에 따른 부유체(21)의 이동을 포토인터럽터(26)의 광검출기(28)의 영역중 수광에 의해 온이 되는 영역의 주소신호가 잉크의 잔량정보에 대응하게 된다.The level detecting unit 20 is provided to provide remaining amount information of the developing ink provided to the developing machine of the printer engine 14, and can be provided by various methods. In the illustrated example, the level detecting unit 20 is made of a material having a lower specific gravity than the ink. It is possible to provide the storage level information of the ink stored using the fluid 21. One of the two arms 23 and 24 connected to each other in a region where the hinge shaft 22 is installed is connected to the floating body 21 and on the movement path of the other arm 24. The photo interrupter 26 is provided. The photointerrupter 26 is installed at one side of the photodetector 27 and the arm 24 having a plurality of areas divided into a line along the movement path of the arm 24 in units of low water levels to be detected. It has a light source 28 which allows light beam spots to form into partitioned unit regions of the photodetector. Accordingly, the address signal of the area where the movement of the floating body 21 due to the variation in the low water level of the ink in the container 25 is turned on by light reception in the area of the photodetector 28 of the photointerrupter 26 is the remaining amount information of the ink. Corresponding to.

도시된 구성의 인쇄기(10)는 외형적으로 종래의 인쇄기의 구성과 유사하지만, 상기 인쇄기 콘트롤러(11)에서 접속된 사용자 컴퓨터(30) 또는 표시장치(13)에 제공하는 상태정보중 인쇄가능 용지매수에 대한 정보를 제공할 수 있는 점에 그 특징이 있다. 이를 위해 레벨검출부(20)에서는 잉크잔량에 대한 정보를 정량적으로 생성하여 인쇄기 콘트롤러(11)에 상시로 제공해주고, 인쇄기 콘트롤러(11)는 그 내부에 마련된 연산프로그램에 의해 잉크잔량으로부터 인쇄가능한 용지의 매수를 산출하여 그 결과값을 기억장치(12)의 상태정보 저장주소에 저장시킨다. The printing press 10 of the illustrated configuration is similar in appearance to a conventional printing press, but printable paper of the status information provided to the user computer 30 or the display device 13 connected by the printing press controller 11. The feature is that it can provide information on the number of copies. To this end, the level detection unit 20 quantitatively generates information on the remaining ink level and provides it to the printer controller 11 at all times, and the printer controller 11 supplies the printable paper from the remaining ink level by a calculation program provided therein. The number of sheets is calculated and the result is stored in the state information storage address of the storage device 12.

인쇄가능한 용지의 매수를 산출하기 위해 인쇄기 콘트롤러(11) 내부에서 실행되는 인쇄가능매수 연산은 다양한 방법이 적용될 수 있고, 간단하게는 설정된 용지 1매를 설정된 이미지 패턴에 대해서 설정된 농도로 인쇄하는데 소요되는 잉크의 량을 단위잉크량으로 하여 잉크잔량을 나눈값을 인쇄가능한 용지의 매수정보로 제공하도록 결정될 수 있다. The calculation of the number of prints performed inside the printer controller 11 to calculate the number of printable sheets can be performed in various ways, and it is simply required to print one set sheet at a set density for a set image pattern. It can be determined to provide the number of sheets of printable paper as information on the number of printable sheets by dividing the ink remaining amount by making the amount of ink a unit ink amount.

이와 같이 산정된 인쇄가능한 용지의 매수정보는 기억장치(12)에 저장된다. 인쇄기 콘트롤러(11)의 인쇄가능한 용지의 매수정보 산정시기는 인쇄작업이 행해질 때마다 잉크는 소비되기 때문에 지시된 인쇄작업이 완료된 이후에 매번 잔류 잉크량을 확인하고, 그에 따라 산정된 인쇄가능한 용지 매수를 기억장치(12)의 설정된 상태정보주소지에 갱신하여 저장시키면 된다. 한번 저장된 인쇄가능한 용지 매수정보는 다음 인쇄작업이 행해지기 전까지는 동일하기 때문에 다음 인쇄작업 지시가 하달될 때까지는 상태정보로서 최근 업데이트되어 갱신된 인쇄가능한 용지 매수정보를 표시장치(13) 또는 접속된 컴퓨터(30)에 제공하면 된다.Information on the number of sheets of printable paper calculated in this way is stored in the storage device 12. The timing of calculating the number of printable sheets of the printer controller 11 is that ink is consumed every time a print job is performed, so that the remaining ink amount is checked each time after the indicated print job is completed, and the number of printable sheets calculated accordingly. May be updated and stored in the set status information address of the storage device 12. Since the information on the number of printable sheets stored once is the same until the next print job is performed, the display device 13 or connected to display recently updated and updated information on the number of printable sheets until the next print job instruction is issued. What is necessary is just to provide it to the computer 30.

이와 같이 인쇄기(10)가 접속된 사용자 컴퓨터(30)에 인쇄작업 하달전에 요구하는 상태정보 전송시 인쇄가능한 용지의 매수정보를 함께 제공하게 되면, 사용자 컴퓨터는 이 정보를 판독한 후, 적절한 방법으로 사용자에게 알려줄 수 있다. 예컨데, 지금 하달한 인쇄작업은 소정 페이지 분량인데 인쇄기(10)의 잔류 잉크량이 부족하여 전체 페이지를 모두 인쇄하지 못하지만, 일부 페이지는 인쇄가능하다는 정보를 제공하고, 인쇄지시를 계속 진행시키겠느냐는 확인 절차를 밟는 사용자 판단 단계를 거치도록 할 수 있게 해준다.In this way, when the printer 10 is provided with the number of printable sheets at the time of sending the status information required one month before the print job to the connected user computer 30, the user computer reads this information, You can tell the user. For example, the print job that has been completed now is a predetermined amount of pages, but the remaining ink level of the printer 10 is insufficient to print all the pages, but it provides information that some pages are printable and confirms whether to continue the printing instruction. Allows you to go through a user judgment step of the procedure.

지금까지 설명된 바와 같이 본 발명에 따른 인쇄기에 의하면, 인쇄기의 인쇄작업 능력에 관련된 상태정보로서 현재 남아 있는 잉크의 잔량정보를 얻어 인쇄가능 용지매수정보를 제공할 수 있도록 함으로써 사용자의 인쇄기 이용을 보다 편리하게 한다.As described above, according to the printing machine according to the present invention, the remaining information of the ink remaining as the status information related to the printing operation capability of the printing machine can be obtained to provide printable sheet number information, thereby making the user's use of the printing press easier. Make it convenient.
