Duplexer
The duplexer driver controls the duplexer operation. An 8-bit microprocessor in the duplexer driver
controls the duplexer sequence and the communication with the dc controller PCA.
The duplexer driver drives the solenoid, motors, and fan according to commands that the dc
controller PCA sends to the duplexer. The duplexer also communicates its status to the dc controller
PCA.
The printer delivers a charge of +24 Vdc to the duplexer, which then generates +5 V for the
integrated circuits.
