Duplex Section - Lexmark MX910de Service Manual

Duplex section

Upper duplex transport
For a duplex print job, the paper is fed back to print on the other side.
The redrive roller, which is driven by the motor (redrive), reverses rotation to feed the paper back to the printer. The
path to the fuser section is closed by the diverter so that the paper moves along the duplex path.
As paper moves down passing the duplex entrance roller and the upper duplex transport roller, the sensor (duplex pass
through 1) detects the position of the paper. The motor (duplex transport) drives the duplex entrance roller and upper
duplex transport roller.
