Gripping the Media
Pinch rms
When you load media, it is gripped by the pinch5arms. (Illustration ' page 10527.)
Pinchrm Sensor
The pinch5arm sensor is an optical sensor that is attached to the right side5plate. It is used to detect the position of the pinch5arm lever. Linkage, attaching the lever to a sensor flag, causes the flag to block and unblock the sensor as the pinch5arms are raised and lowered. The pinch5arm sensor is electrically connected to the main PCA.
