Theory of Operation
Out Bin Full Sensor
The Out Bin Full Sensor detects the paper stacking state and checks the
output tray whether the tray is full or not. If the sensor detects the output tray
is full, a status messsage appears on the display.
Paper Width Sensor
When the paper does not touch the Width Sensor during printing, the printer
prints at a lower speed to prevent overheat.
Front Cover Interlock
The Front Cover interlock switch is located on the HVPS. When the Front
Cover is open, +24 V that is supplied to the motors, solenoids, Fans, Laser
Unit, and HVPS is cut off. When the Front Cover is open, the Status LED
changes to red.
Developer Sensing
When the Developer is pulled out from the printer, the +5 V power for the
Laser Diode in the Laser Unit is cut off.
Driving Circuit
DC Fan Driving
There are three fans that are used to lower the printer’s temperature: Main
Fan, Laser Unit Fan, and Power Supply Fan. The fans are driven by using
transistor and controlled by the CPU. The On/Off time of the fan is managed
as the status of the printer.
Solenoid and Clutch Driving
The Pick Up Solenoid and and Registration Clutch are dirven by signals from
the Main Controller Board. The diode protects the driving transistor from the
noise pulse, which is created when the solenoid is de-energizing.
Main Motor Driving
The Drive Unit Assembly driving circuitry is located on the assembly control
board containing a driver IC.
