6.9.5 DEVELOPMENT UNIT CONTACT MECHANISM

Mechanism

Each development unit has an independent clutch. When a development clutch
turns on, a gear under the development unit moves the development unit into
contact with the OPC belt. When the clutch turns off, two springs (one at the front
and one at the rear) detach the development unit from the OPC belt.
