AcuLaser M2000D/M2000DN/M2010D/M2010DN Revision BOPERATING PRINCIPLES      Technical Explanation of Print Process 222.2.3  DevelopmentThe latent image constituted on the drum is developed into a visible image. The developing roller contains a 3-pole (S-NS) magnet roller and an aluminum cylinder rotating around the magnet roller. Toner attracts to the magnet sleeve since it is powdery ink made of black resin bound to iron particles. Developing blade, magnetized by magnet, is positioned approximately 0.3...

AcuLaser M2000D/M2000DN/M2010D/M2010DN Revision BOPERATING PRINCIPLES      Technical Explanation of Print Process 232.2.4  Transfer/SeparationThe transfer/separation section consists of the transfer roller, discharger brush and paper chute guide. A high voltage generated by the HVPS (High Voltage Power Supply) is applied to the transfer roller for transfer charging. Paper after transfer is separated from the drum.

AcuLaser M2000D/M2000DN/M2010D/M2010DN Revision BOPERATING PRINCIPLES      Technical Explanation of Print Process 242.2.5  CleaningAfter the transferring process, the drum needs to be physically cleaned of toner which is residual after the development process. The cleaning blade is constantly pressed against the drum and scrapes the residual toner off to the sweep roller. The waste toner is collected at the output end of the sweep roller and sent back to the toner container, into the waste toner...

AcuLaser M2000D/M2000DN/M2010D/M2010DN Revision BOPERATING PRINCIPLES      Technical Explanation of Print Process 252.2.6  FusingThe toner on the paper is molten and pressed into the paper as it passes between the heat roller and the press roller in the fuser unit. The heat roller has a heater lamp inside which continuously turns on and off by the fuser thermistor to maintain the constant temperature onto the heat roller surface. The heat roller is resin coated by florin to prevent toner from...

AcuLaser M2000D/M2000DN/M2010D/M2010DN Revision BOPERATING PRINCIPLES      Technical Explanation of Print Process 262.2.7  Paper exit sectionThe paper exit section transports the paper which passed the fuser unit towards the top tray. The paper which passed through the fuser unit turns on the actuator (exit sensor) in the fuser unit, and is led by the guide comprised of the rear cover, frame and the FD cover guide, finally reaching the upper FD roller. The paper is delivered to the top tray by the...
