Loading the Media
Entry Platen
The media load path begins with the entry platen, which provides a loading surface. (Illustration ' page 10523.)
When you assemble the plotter, it is important to correctly position the entry platen to ensure that the dashed lines exactly indicate the permitted right5edge loading area. The left side of the entry platen should be pressed up against the left side5plate. (Details ' chapter 6.)

Sensing Media Presence
Media Sensor
The media sensor is an optosensor and is mounted towards the right end of the entry platen. (Illustration ' page 10523). Two articulated levers block the optical path between emitter and receiver when media is not loaded. When media is loaded, both levers are rotated, thus clearing the optical path and changing the sensor state from open to closed. This double5lever system provides a leading and trailing edge5sensing capability (for media5length measurement) to the plotter. The media sensor is electrically connected to the main PCA.
