2.1.5 Paper Paths
This section describes various paper paths through the printer mechanism. These paper paths are divided into
four groups, depending on which entrance (top, rear, bottom, or front) is used to feed paper. The printer has
two PE (paper end) sensors. The front PE sensor is located in front of the printer mechanism. The rear PE
sensoris located behind the printermechanism. Refer to thefollowing figure.
