Principles of Operation

Paper Paths

This section describes the various paths the paper follows through the printer mechanism. These
paper paths are divided into four groups, depending on the entrance the paper is fed from (top, rear,
bottom, or front).
Note: The front paper-end (PE) sensor is located in front of the printer mechanism and the rear
PE sensor is located behind the printer mechanism.
Top Entrance
Figure 6-12 shows the paper path for friction feeding using the top entrance. The top entrance is
used only for the friction feed method. When the top entrance is used, the rear PE sensor senses
when paper is out.
