Abstract

레이저프린터의 현상 방법 Developing method of laser printer

Description

레이저프린터의 현상 방법 {laser printer develop method}Developing method of laser printer {laser printer develop method}

음이 대전특성을 갖는 유기 감광체와 소형 캐리어를 사용하여 높은 해상도와 농도의 프린트를 행한다A print with high resolution and density is carried out using an organic photoconductor having a negative charging characteristic and a small carrier.

컴퓨터 프린터Computer printer

프린터의 해상도를 높인다.Increase the resolution of the printer.

유기감광체드럼(1)은 음의 대전 특성을 가지며 전하를 보지하고 대전부(2)는 코로나 방전을 이용하여 감광체 전면을 일정전위로 대전시킨다. 노광부(3)는 컴퓨터의 신호를 인지하여 감광체의 일정부위에 레이저를 주사하므로써 전위를 낮추어 정전잠상을 형성한다. 또 현상부(4)에서 비자성체 슬리이브(4e)에 포삽된 현상자극(46)은 교반기(4c)에서 마찰대전된 현상제를 브러쉬상으로 형성한다. 이때 현상제는 토너와 철분 캐리어가 혼합되어 있고 비자성 도전성 물질이 절단부(4g) 사이로 300-800 마이크로미터의 절단간격(B) 만큼 절단되며 슬리이브의 회전에 따라 감 광체와 슬리이브의 현상간격(A)을 400-1100마이크로미터로 유지하면서 토너가 감광체에 현상된다. 이때 토너농도센서(4h)가 토너공급롤러(4b)를 제어하고 현상된 토너는 전사부(5)에서 용지(10)위로 이동된다. 이때 폴리우레탄재질의 클리이닝부(6)는 잔류토너를 제거하고 제전부(7)는 감광체 위의 잔류전위를 소멸한다. The organophotoreceptor drum 1 has negative charging characteristics and retains charge, and the charging unit 2 charges the entire surface of the photoreceptor to a constant potential by using corona discharge. The exposure section 3 recognizes a signal from a computer and scans a laser at a predetermined portion of the photoconductor to lower the potential to form an electrostatic latent image. In addition, the developing stimulus 46 inserted into the nonmagnetic sleeve 4e in the developing section 4 forms a developer tribally charged in the stirrer 4c in the form of a brush. At this time, the developer is mixed with the toner and the iron carrier, the nonmagnetic conductive material is cut by the cutting interval (B) of 300-800 micrometers between the cutting portion (4g) and the development interval between the photosensitive member and the sleeve as the sleeve rotates. The toner is developed on the photosensitive member while maintaining (A) at 400-1100 micrometers. At this time, the toner concentration sensor 4h controls the toner supply roller 4b and the developed toner is moved from the transfer section 5 onto the paper 10. At this time, the polyurethane cleaning unit 6 removes the residual toner and the static eliminator 7 dissipates the residual potential on the photoconductor.

프린트의 해상도와 농도가 높아진다.The print resolution and density increase.
