11. LIFT MECHANISM

The lift spring [A] resists the weight of the belt unit, making it easier to lift the belt unit.
When the belt unit is lifted, the detent arm [6] turns on the lift switch. At the same time, the DF
CPU sends a signal to the copier CPU. This signal enables the copier to operate without the
document feeder. While the lift switch is on, the DF modes are prohibited.
