OutlineThe printer unit switches between face-up and face-down delivery paths using thedelivery flapper.The face-up delivery roller and the face-down delivery roller are driven by the mainmotor (M4); when the face-up solenoid drive signal (FUSLD*) goes ‘0’, the face-up sole-noid (SL2) operates the face-up flapper so that it will face the face-up tray, deliveringpaper to the face-up tray. When FUSLD* is ‘1’, on the other hand, paper will be deliveredto the face-down tray found at the top of the printer unit.Paper on the face-down tray is checked by the face-down tray delivery sensor (PS11).When the face-down tray becomes full of paper, the condition is identified by the face-down tray full sensor (PS10).Figure 5-301CHAPTER 5 PICK-UP/FEEDING SYSTEM5-21q : Face-up solenoid drive signal (FUSLD*)w : Face-down tray delivery paper signal (FDOUT*)e : Face-down full detection signal (FDFULL)r : Main motor drive signal (MON*)ew rqUpper fixing rollerLower fixing rollerDelivery flapperFixingdeliveryFace-downdelivery rollerPS10DC controller PCBPS11PS10: Face-down tray full sensorPS11: Face-down delivery paper sensorSL2: Face-up solenoidM4: Main motorFace-updelivery rollerSL2M4Developing rotary motor PCB Face-downdelivery trayFace-updelivery trayDownload free service manual at http://printer1.blogspot.com
