Image Drum Unit
The image drum unit consists of a sensitive drum, a charger, and a developer. The unit forms a toner
image on the sensitive drum, using a electrostatic latent image formed by the LED head.
Registration Motor
The registration motor is a pulse motor of 48 steps/rotation, that is two-phase excited by the signal from
the Main Control PCB. It drives the hopping and registration rollers via two one-way clutches according to
the direction of rotation.
Drum Motor
The drum motor is a pulse motor of 48 steps/rotation that is two-phase excited by the signal from the Main
Control PCB and is the main motor of this mechanism.
LED Head
Image data for each dot line from the control board is received by the shift register and latch register. The
2496 LED's (OKIPAGE 6e)/4992 LED's (OKIPAGE 6ex) are driven to radiate the image data on the image
drum.
Fuser
The fuser consists of a heater, a heat roller, a thermistor and a thermostat.
The AC voltage from the power supply board is applied to the heater controlled by the HEATON signal
from the control board. This AC voltage heats the heater. The Main Control PCB monitors the heat roller
temperature via the thermistor, and regulates the heater roller to a predetermined temperature (165°C) by
connecting or disconnecting the AC voltage supply to the heater.
When an abnormal rise of the heater roller temperature takes place, the thermostat of the heater voltage
supply circuit becomes active and forcibly cuts the AC voltage supply.
