Chapter 761The image processor comes in different ROM types/sizes and RAM sizes according to models.The firmware stored in the flash ROM may be either SYSTEM or BOOT.Using the service support tool, the following 3 types of firmware may be upgraded: SYSTEM and BOOT stored in the flash ROM and the firmware stored ion PCLROM.F-7-37.1.4 DC Controller PCB 0013-1077/ / / / iR1018 / iR1018J / / iR1022A / iR1022F / iR1022i / iR1022iF /Fixing Heater Control BlockThe fixing heater control block monitors the temperature reading of the thermistor to ensure that the temperature of the heater reaches a specific level. If an erroris detected in the temperature of the heater, it stops the power to the heater.High-Voltage Control BlockThe high-voltage control block controls the high voltage for the primary charging roller, developing cylinder of the cartridge, transfer charging roller, and fixingfilm.Drive Control BlockThe drive control block controls the main motor, pickup solenoid, and fan.Sensor DetectionIt detects the state of the sensors in the pickup assemblies and the printer block, thereby monitoring the drive assembly.Image Processor PCB Interface blockThe image processor PCB interface block sends the horizontal sync signal (BD0*) to the image processor PCB. It also returns a state signal in response to a com-mand signal (serial) from the image processor PCB, thereby communicating the state of the printer block to theimage processor PCB.Laser Control BlockThe laser control block controls the drive of the laser diode of the laser scanner unit according to the image signals (VD01, VD01*, VD02, VD02*) from the imageprocessor PCB. Also, it controls the intensity of the laser diode (auto power control) for each line of print data.Horizontal Sync Signal ControlWhen the laser beam reaches the horizontal print start position, the laser beam detection signal (BDI*) from the laser scanner unit is detected, and the horizontalsync signal (BD0*) is sent to the image processor PCB. Also, the horizontal sync signal (BD*) is monitored for frequency of output.Scanner Motor ControlThe scanner motor is controlled so that the horizontal resolution of the print image is 600 dpi. Also, the laser beam detection signal (BDI*) from the laser scannerunit is detected to monitor the rotation of the scanner motor.Drum Unit Detection MechanismIn wait state, the CPU on the DC controller PCB measures the voltage level of the cartridge detection signal (CRGSNS) a specific number of times to check thepresence/absence of the drum unit when an AC bias is applied to the primary charging roller.CPUImage processor PCBDDR-SDRAM (256MB)USB MEMORY (128MB)Flash ROM (16MB)PCL ROM (16MB)CPUImage processor PCBDDR-SDRAM (128MB) Flash ROM (16MB)CPUImage processor PCBDDR-SDRAM (64MB) Flash ROM (12MB)
