3. 1. 2. 1 Erasing (Removal of negative electric charges)
As the first step of print cycle, it is necessary to remove the negative electric charges from the
Drum, which have remained there after the former print cycle.
The Drum has a characteristic to lose the negative electric charges if it is exposed to the light.
So the Drum is rotated and evenly exposed to the light from the Eraser Lamp.
The electric potential on the Drum becomes 0V (residual potential) by this process.
