Duplexing unit (duplex models)
For supported models, the duplexing unit reverses the paper and feeds it through the paper path to
print the second side. The duplexing unit consists of the following components:
Duplexing-reverse unit: Installed on top of the product
Duplexing-feed unit: Along the right side
The DC controller controls the operational sequence of the duplex block. The DC controller drives each
load, such as motors, solenoid, and clutch, depending on the duplex reverse unit and duplex feed unit
controls.
