imageCLASS MF9170c / imageCLASS MF9150c / imageCLASS MF8450c
In duplexing printing, the machine reverses the paper printed on the first side and again transports it to the pickup position to print the second side.
Paper reverse is driven by the reverse motor (M11) and duplexing solenoid (SL5017).
The duplexing feed assembly feeds the paper by rotating two skew rollers by the duplexing feed motor (M10).
When the registration sensor (SR710) detects the lead edge of the paper, it sends a signal to the DC controller. The reverse driver PCB detects whether the paper
has been transported to the pickup position or not by monitoring the signal.
