After the operations are ended, restore the paper feed pressure and separation
pressure.
If copy paper or fine quality paper is used in the setting of art paper or coated paper, the strong
paper feed pressure could cause two-sheet feeds, while the strong separation pressure could
cause damage to the front edges of the paper.
