Cleaning Blade Pressure/Retraction Mechanism
■ During color printing, an image is formed on the Transfer Belt for each color of toner. The
Cleaning Blade is therefore provided with a pressure/retraction mechanism. that moves the
cleaning blade and applies pressure at the correct time.
■ In monochrome printing, no retraction sequence is carried out.
■ The Cleaning Blade is normally in contact with the Transfer Belt.
Pressure/Retraction Operation
■ The Cleaning Blade pressure/retraction operations are performed by the Main Motor
(M1), Pressure/Retraction Solenoid /Cleaning Blade (SL3), pressure cam, lever, and
Retraction Position Sensor /Cleaning Blade (PC6).
■ When the Pressure/Retraction Solenoid /Cleaning Blade (SL3) is energized, drive from the
Main Motor (M1) is transmitted to the pressure cam.
