2.6.3 PAPER FEED/SEPARATION PRESSURE ADJUSTMENT
MECHANISM
Overview
The paper separation pressure and the paper feed pressure depend on the paper
type selected at the operation panel. When the paper type is changed, two dc
motors automatically turn to change the pressure settings.

The paper separation pressure is applied from the bottom of the friction pad block
[A] by a spring on the friction pad base [E].
The direction of the paper separation pressure motor [B] turn depends on the
signal from the CPU. The rack [D] moves from side to side, moving the friction pad
base up or down. This changes the spring pressure against the friction pad block.
The position of the rack [D] is detected by the separation pressure detection board
[C].
