DEFINITION

Classification: 400/707.1

Drive initiated by detector of record-medium:

(under subclass 707) Subject matter wherein the device is provided with means to sense a characteristic of the record-medium* and said means causes connection of the device with the platen* to move the device.

(1) Note. Usually the sensor detects the trailing end of a sheet (i.e., the absence of a sheet that has moved past a particular location). However, this subclass also provides for a sensor to detect an index mark, a hole or notch, an area of magnetically oriented particles on the sheet, or any other indication that a particular point on the sheet has reached a particular location.
