8.3.5 Pick-up Roller Pressure Mechanism

This by-pass feed table uses a pick-up roller pressure mechanism, which

has two pick-up solenoids. This system uses the main pick-up solenoid [A]

and the sub pick-up solenoid [B] to change the pick-up roller pressure, to

adapt to various paper types and copy modes.

The pick-up roller is lifted by springs [C] on the arm when the copier is not

operated. When the copier is started, the pick-up roller is lowered onto the

paper by the main pick-up solenoid spring [D]. The sub pick-up solenoid

assists the main pick-up solenoid to increase the pressure via the sub

pick-up solenoid spring [E].
