Theory of Operation Ver. 1.0 Nov. 2005
(1) Pressure sequence
1. Drive from the Main Motor (M1) is transmitted to the drive gear.
2. Rotation of the drive gear is transmitted to the Pressure/Retraction Clutch.
3. When the Pressure/Retraction Solenoid /2nd Image Transfer (SD4) is energized,
the Pressure/Retraction Clutch rotates a half turn. This moves the Pressure Slider.
4. When the Pressure Slider is moved, ribs on the Pressure Slider push up the 2nd
Transfer Assy.
5. When the 2nd Transfer Assy is pushed up, the 2nd Transfer Roller is pressed up
against the Transfer Belt.

(2) Retraction sequence
1. When the Pressure/Retraction Solenoid /2nd Image Transfer (SD4) is energized in
the condition in which the 2nd Transfer Roller is pressed against the Transfer Belt,
the Pressure/Retraction Clutch rotates a half turn. This moves the Pressure Slider.
2. When the Pressure Slider is moved, the 2nd Transfer Assy, which has been pushed
up by the ribs on the Pressure Slider, lowers.
3. When the 2nd Transfer Assy lowers, it allows the 2nd Transfer Roller to be retracted
from the Transfer Belt.
