■ When the 2nd Transfer Assy is pushed up, the 2nd Transfer Roller is pressed up against
the Transfer Belt.
Retraction Sequence
1. When the Pressure/Retraction Solenoid /2nd Image Transfer (SL4) 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.
