Pressure Control Mechanism - Ricoh Beluga-C1 Training

Pressure Control Mechanism

Motor
Fusing pressure motors: Adjust the pressure between the hot and pressure
rollers for each sheet of paper.
The amount of the adjustment depends on:
Machine type (D046/D154, D049/D155), Paper type, Hot roller temperature
If a jam occurs, the pressure is released automatically, so the user can
remove the paper.

Each motor pulls a spring, which moves a lever that applies upward pressure on
the end of the pressure roller shaft.
The pressure roller is hollow, so the shaft does not affect the pressure at the
ends of the pressure roller. Bushings at the centre of the shaft push upwards,
and this applies the upward pressure between the hot roller and pressure roller.
Details of the process for D046/D154 are different from D049/D155.
The release position for removing jams is not the same as the home position.
The output tests (SP 5804) have two different settings: For the home
position and for the jam release position
