FO-4400U FO-CS1 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-4400U FO-CS1 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-4400U FO-CS1 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.
