FO-DC500U 5. PAPER PATH Paper can be fed into the printer from the Multi Purpose Tray (250 sheets) or from the Manual Feed Port (1 sheet). Installing the 2nd Paper Cassette Unit (FO-CS1) (500sheets) adds another feeding method. The paper fed by the Paper Take-Up Roller is transported to the Image Transfer Roller, Fusing Roller and then Paper Exit Roller. After this, the paper is fed out onto the Print Tray.
FO-DC500U 8. LASER EXPOSURE Reflector Mirror Laser exposure is the process of creating an invisible static charge image on the PC Drum by the laser beam emitted from the Print Head Unit. This process is controlled as follows in order to appropriately time image printing. In the sub-scanning direction (vertical direction) · When the printer receives the PRINT signal, the Polygon Motor and the Main Motor rotate and the paper is fed into the printer.
FO-DC500U 10. IMAGE TRANSFER 11-2. Fusing Temperature Control Circuit 10-1. Overview · The Thermistor (TH1) detects the surface temperature of the Heat Roller and inputs that analog voltage into IC4-78. Corresponding to this data, the Heater Lamp (H1) ON/OFF signal is output from IC4-55, causing the Heater Lamp (H1) to turn ON or OFF to control the fusing temperature.
FO-DC500U 12. PRINT SEQUENCE Printing is carried out following communication between the engine and controller that determines the timing to be used. A general outline of the printing sequence is described below. Controller Engine /PRINT Initiates the printing command. Prepares for printing - Print head - Feeds a sheet of paper, etc. Receives the vertical direction synchronizing signal. /TOD Receives the mainscanning direction synchronizing signal.
