KX-P7100 1.7. 1.7.1. Print Process Charge The charge corona applies a high, uniform positive charge to the surface of the organic photoconductor ( OPC ) drum. The charge level is approximately 900 VDC and remains because the OPC drum has a high electrical resistance when concealed in darkness. 1.7.2. Exposure The laser beam passes through the collimator lens, is reflected by the polygon mirror, and is focused onto the drum after passing through an image-forming ( ) lens and a reflectionmirror.
KX-P7100 Cleaning: After transfer, residual toner remains on the drum surface, and for next printing, the residual toner reaches to the development area via charge and exposure. The charge level of the OPC corresponds to the white background is +900VDC, andthe bias voltage of the conductive roller is approx. +350VDC. Therefor the positively charged residual toner on the OPC drum is attracted and collected to the conductive roller. The charge level of OPC after exposure is +100VDC.
KX-P7100 1.8. Paper Feed Media Tray The main motor drives the pickup roller after the pickup solenoid is energized, which engages the pickup roller clutch and feeds a sheet of paper. The paper is pushed to the paper feed roller, which overdrives the paper slightly causing a buckleto ensure the paper is aligned with the stationary registration roller. While triggering the registration sensor notifying the CPU paper is ready to feed. The paper at this point is the same as manual feed.
KX-P7100 1.9. 1.9.1. Laser Scan Unit ( Exposure ) Operation Theory The light beam from the laser diode ( light source ) is modulated by the digital signal (nVIDEO) and converted to parallel light waves by the collimator lens. The beam is then sent to the rotating polygon mirror (polygon scanner), where it is reflectedthrough the lens and then focused onto the OPC drum surface.
KX-P7100 1.9.3. Collimator Lens The collimator lens converts light from the laser diode to parallel light. This aids in scanning and provides better convergence to a dot. 1.9.4. Polygon Scanner The polygon scanner consists of a 6-sided mirror directly driven by a brushless DC motor at a rate 20,078.74 rpm. The laser beam is reflected across the OPC drum by the mirror faces and produces the scan. One mirror face is equal to one main scan.
KX-P7100 1.10. Fuser Unit A 600W heat lamp ( halogen lamp ) heats the surface of the teflon-coated heat roller to approximately 190°C ( 374°F ), a thermistor monitors the heat roller temperature, and the CPU controls the ON/OFF timing of the lamp. The thermostat is mounted 2.5mm away from the heat roller. If the ambient temperature reaches 180°C ( 356°F ), the thermostat is opened, and power is removed from the heat lamp. The surface of the thermostat is not as hot as thatof the heat roller.
KX-P7100 1.11. Paper Ejection and Paper Switchback A. Normal Printing Mode ( Not Duplex Mode ) After fusing, paper is fed to the output tray by the switchback roller and switchback pinch roller. The paper exit/ADU paper jam sensor detects paper. If paper does not arrive at the sensor within a predetermined period of time, “Jamat A” is displayed, and if paper remains at the sensor beyond a predetermined period, “Jam at B” is displayed on the computer screen.
