LQ-2070 Service Manual Operating Principles 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 sensor is located behind the printer mechanism. See the figure below. Printhead Paper Eject Drive Roller (Paper Eject Assembly) Platen Platen Cover Middle Paper Guide Paper Drive Roller Front Paper Guide Front PE Sensor Rear PE Sensor Rear Driven PF Roller Front Driven PF Roller Lower Driven PF Roller 1. Top Entrance Figure 2-12 shows the paper path for friction feed using the top entrance. The top entrance is only used with the friction feed method. When the top entrance is used, the rear PE sensor detects when the paper is out. Up Up Rev.A 2-11
