Exposure The light rom LED Head is exposed on the negative-charged surace o image drum. The surace electrical potential o the exposed part o image drum surace becomes lower. Then orms electrostatic latent image. 3. Development Negative-charged toner is attracted to the electrostatic latent image due to electrostatic while touching the image drum. Then orms viewable image. 4. Transer Overlap paper on the surace o OPC drum, rom the backside o paper transer toner image to the paper by applying electrical charge by transer roller. 5. Fusing The toner image that is transerred to paper is used on paper by heat and pressure. 6. Drum cleaning The cleaning blade scrapes o the toner that was not transerred and remains on the image drum. 7.

When the surace electric potential o exposed part o the image drum goes to decrease, the electrostatic latent image complying with image signal is ormed. Image drum is coated by basic layer (UL), charge generating layer (CGL), charge transerring layer (CTL) on the basic material aluminum. The thickness o the organic light sensor (OPC) that is consisted by CTL and CGL is approximate 20µm.

The transer roller, which is rom conductive sponge material, is created to meet intimate attachment o image drum roller surace and eeding paper. The eeding paper is set up on the surace o image drum. Plus charge, which is the converse polarity with toner polarity, is applied rom the backside o the paper. As high plus voltage is applied to transer roller rom the power supply, the plus charge on the transer roller surace is induced and transerred to the paper while the paper contact the transer roller. The negative charged toner, which has been attracted to the image drum surace, is transerred to the surace o eeding paper by the plus charge o the backside o the paper. Image drum

Heat roller is Tefon coated and is mounted by heater that can generate heat (Halogen lamp). The thermistor that contacts the Heat roller adjusts the Heat roller temperature to the temperature specied by the menu complying with the paper width. For saety the thermostat shuts o the voltage supply to the Heater by opening the thermostat in the case o abnormally temperature increasing. The back up roller is held by the pressure springs on each terminal due to the pressure applied.

2.2 Printing process The paper ed rom Tray 1 and Tray 2 is conveyed by eeding roller, conveying roller, and resist roller. When eeding paper is rom MPT, it is conveyed conveyed by MPT, MPT, eeding roller, and resist roller. Ater that the eeding paper that is conveyed by image drum and the nip part o transer roller orms toner image on the paper through electrophotographic electrophotogra phic process. And then, the toner on the paper is used by the heat and pressure as the user unit passing through. The paper that used the toner image is ejected rom the ace down stacker o the ejecting roller. To eject printed pages on the ace-up stacker, open the ace-up stacker. (Duplex printing is not available during ace-up ejection.) The above is about the operations at simplex printing, yet the below explains the operations at duplex printing. While duplex printing, paper, which rstly passes the user unit ater its backside is printed, is conveyed to the inside o the duplex unit, by the reverse rotation o the rst and the second ejecting rollers in a certain period o time ater the paper rear end passes the user unit. The paper is conveyed by the conveying roller o the duplex unit and then arrives the route or paper eeding rom a tray. Ater that, the paper is handled in the same way as paper ed rom a tray or simplex printing.

2.3 Toner entrance detection Toner sensor detection principle Toner low is detected by the toner sensor (refect sensor) installed in the printer. The light shield plate is installed in the ID, and its rotation is synchronized with mixing o toner. I the light shield plate or toner sensor is dirty with toner or something, or the ID unit and the toner sensor are acing each other at an improper position due to improper setting o the ID unit or any reasons, toner low cannot be detected correctly, and a toner sensor error occurs.

Toner sensor Light board

Toner count principle Ater the image data is transormed into binary data which can be printed by the printer, the data is counted as print dot number by LSI. The amount o the used toner is calculated rom this count value, and the residual amount is displayed on the menu. Toner LOW detection (residual amount display on LCD) by the toner sensor is to detect a certain amount o the reduction o the toner let in ID.

Description Descripti on or Operation o Second Tray unit

Second Tray unit receives a signal rom the printer main body and eeds paper to the printer main body. Paper Feed rom the Second Tray unit (Tray2) 1.

When a signal is received rom the printer main body, the pulse motor is rotated (Counterclockwise (Counterclock wise rotation), and by setting the paper eed clutch to ON, the paper eed roller and pick-up roller are rotated. Thereore, paper in a tray is ed.

2. Ater hitting the entrance sensor lever and switching the sensor to ON, the paper runs into the conveying roller (Tray 2) that is at rest, and then it is conveyed urther by a certain amount. (This action corrects the paper skew.) 3. By setting the regist clutch to ON, the paper is carried by the regist roller. roller.
