To properly position the sensor you will need to know where the TOF
mark is located on your media. (For more information on media, see
Specifications).
Depending of your media type, take a measurement from the left-
justified media edge across to the center of the TOF mark. The following
example illustrates the measurement of notched media.
Note: Reflective marks are placed on the underside of the media.
The sensor uses Reference Letter designators that correspond to the
following TOF mark distances:
